    Selective potentiometric determination of uric acid with uricase immobilized on ZnO nanowires2011In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 152, no 2, p. 241-247Article in journal (Refereed)
    Abstract [en]

    In this study, a potentiometric uric acid biosensor was fabricated by immobilization of uricase onto zinc oxide (ZnO) nanowires. Zinc oxide nanowires with 80-150 nm in diameter and 900 nm to 1.5 mu m in lengths were grown on the surface of a gold coated flexible plastic substrate. Uricase was electrostatically immobilized on the surface of well aligned ZnO nanowires resulting in a sensitive, selective, stable and reproducible uric acid biosensor. The potentiometric response of the ZnO sensor vs Ag/AgCl reference electrode was found to be linear over a relatively wide logarithmic concentration range (1-650 mu M) suitable for human blood serum. By applying a Nafion (R) membrane on the sensor the linear range could be extended to 1-1000 mu M at the expense of an increased response time from 6.25 s to less than 9 s. On the other hand the membrane increased the sensor durability considerably. The sensor response was unaffected by normal concentrations of common interferents such as ascorbic acid, glucose, and urea.

    Polymer nanoliter well arrays for liquid storage and rapid on-demand electrochemical release2018In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, no 267, p. 111-118Article in journal (Refereed)
    Abstract [en]

    Polymer microfluidic systems are of increasing importance in several applications in biomedicine andbiosensing. The integrated encapsulation, storage, and controlled release of small amounts of liquid insuch systems remains an unresolved technical challenge. Here, we report two methods for the room-temperature and adhesive-free sealing of 1–330 nanoliter volumes of liquid in off-stoichiometry thiol-enepolymer well arrays by spontaneous bonding to 200 nm thin gold films. Sealed well arrays were storedfor more than one month in a liquid environment with <10% liquid loss, and for more than one week inair with minimal loss. We demonstrated that controlling the electrical potential and polarity over encap-sulated wells allowed for selecting one of two well opening mechanisms: slow anodic electrochemicaletching, or rapid electrolytic gas pressure-induced bursting of the gold film. The results may find poten-tial applications in diagnostic testing, in vivo drug delivery, or in spatio-temporal release of chemicalcompounds in biological assays.

    On the performance of gas sensor arrays in open sampling systems using inhibitory support vector machines2013In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 185, no August 2013, p. 462-477Article in journal (Refereed)
    Abstract [en]

    Chemo-resistive transduction presents practical advantages for capturing the spatio-temporal and structural organization of chemical compounds dispersed in different human habitats. In an open sampling system, however, where the chemo-sensory elements are directly exposed to the environment being monitored, the identification and monitoring of chemical substances present a more difficult challenge due to the dispersion mechanisms of gaseous chemical analytes, namely diffusion, turbulence, and advection. The success of such actively changeable practice is influenced by the adequate implementation of algorithmically driven formalisms combined with the appropriate design of experimental protocols. On the basis of this functional joint-formulation, in this study we examine an innovative methodology based on the inhibitory processing mechanisms encountered in the structural assembly of the insect's brain, namely Inhibitory Support Vector Machine (ISVM) applied to training a sensor array platform and evaluate its capabilities relevant to odor detection and identification under complex environmental conditions. We generated - and made publicly available - an extensive and unique dataset with a chemical detection platform consisting of 72 conductometric metal-oxide based chemical sensors in a custom-designed wind tunnel test-bed facility to test our methodology. Our findings suggest that the aforementioned methodology can be a valuable tool to guide the decision of choosing the training conditions for a cost-efficient system calibration as well as an important step toward the understanding of the degradation level of the sensory system when the environmental conditions change.

    Toward development of optical biosensors based on photoluminescence of TiO2 nanoparticles for the detection of Salmonella2017In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 252, p. 95-102Article in journal (Refereed)
    Abstract [en]

    Quality control of food and agriculture production is an inseparable part of human safety and wellbeing. Salmonella infections belong to one of the most monitored pathogens in the world, therefore advanced determination of this pathogen can decrease the risks of human diseases caused by this microorganism. In this research we introduce a novel optical immunosensor for determination of Salmonella typhimurium. The immunosensor is based on Titanium dioxide (TiO2) nanoparticles deposited on glass substrates (glass/TiO2)center dot TiO2 nanoparticles exhibit an intense photoluminescence (PL) in the visible range of spectrum at room temperature. The direct immobilization of antibodies (anti-S-Ab) against Salmonella antigens on the surface of glass/TiO2 has resulted in the formation of glass/TiO2/anti-S-Ab-based structure, which was characterized by increased PL intensity and IR-shifted position of the PL peak in comparison to the same characteristics of glass/TiO2-based structure. The changes of the PL intensity and peak positions after interaction of the immobilized anti-S-Ab with Salmonella antigens (Salmonella-Ag) were used as immunosensor signal, allowing sensitive and selective detection of Salmonella-Ag in a label-free configuration. The sensitivity of the reported optical immunosensor towards Salmonella-Ag is in the range from 10(3) to 10(5) cell/ml. Some aspects of the interaction between TiO2 and biological compounds have been discussed. This work opens up new possibilities for the development of optical label-free immunosensors suitable for fast, simple and efficient analysis of Salmonella infections. (C) 2017 Elsevier B.V.

    Modification of vapor sensitivity in ellipsometric gas sensing by copper deposition in porous silicon2002In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 85, no 1-2, p. 95-103Article in journal (Refereed)
    Abstract [en]

    The sensitivities of porous silicon layers modified by copper deposition to low vapor concentrations of methanol, ethanol and 2-propanol are studied with spectroscopic ellipsometry. The porous silicon layers are prepared with electrochemical etching in hydrofluoric acid, and copper deposition is done in aqueous CuSO4. The ellipsometric vapor sensitivities, in terms of the ellipsometric spectral shifts due to gas exposures, of these samples and their oxides are studied and compared. It is shown that ellipsometric vapor sensitivities of porous silicon layers to alcohols are improved by copper deposition. It is also found that the oxidation of copper deposited in porous silicon layers shows improved selectivity to methanol. © 2002 Elsevier Science B.V. All rights reserved.

    Modulating a D-Π-A type diarylethene for on-demand Cu2+ check via photo-switchable detection range and sensitivity2018In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 257, p. 77-86Article in journal (Refereed)
    Abstract [en]

    Detection range and sensitivity are two important parameters in a sensing system. Unfortunately, in common sensory systems, wide detection range always suffers from low sensitivity and vice versa. Thus, it becomes more and more desirable to design sensors with both wide detection range and high sensitivity. Here, we report a sensory system based on a photo-switchable D-π-A type diarylethene (SDE), which presents both wide detection range and high sensitivity under alternate light modulation. The D-π-A structure endows the sensor with high energy level of HOMO, which enabled the oxidation of both photoisomer SDEo/SDEc by Cu2+. While the discrepancy in energy levels of oxidation potentials in SDE photoisomers leads to their different reactivity, or in another word, sensitivity towards Cu2+. The inherent oxidative cycloreversion of SDEc to SDEo, on the other hand, provides a possibility that two photoisomers would detect Cu2+ in different working concentrations. The open form was employed for the detection of Cu2+ in a wider concentration range (0–13.0 equivalent) with relatively lower sensitivity (6.4 × 10−7 M). While the closed form was able to probe Cu2+ in lower concentration (0–3.0 equivalent) with higher sensitivity (6.6 × 10−9 M). Based on this photo-switchable sensing activity, a molecular multimeter of variable detection range for Cu2+ was then constructed.

    An all-printed wireless humidity sensor label2012In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 166-167, p. 556-561Article in journal (Refereed)
    Abstract [en]

    Printed electronics promise various kinds of sensor circuit labels, for applications in distributed sensing and monitoring, which can be manufactured using traditional printing tools at very low cost. Elevated humidity levels or water leakages cause tremendous costs in our society, such as in construction industries and in transportations. Distributed monitoring and remote sensing of the humidity level inside walls of buildings and packages is therefore desired and urgently needed. Here, we report a wireless humidity sensor label that is manufactured using screen-printing and dry-phase patterning. The sensor label includes a planar antenna, a tuning capacitor and a printed sensor-capacitor head. Through electromagnetic coupling between a reader and the printed sensor label, changes in humidity level were remotely detected and read-out as a shift of the resonant frequency. The manufacturing process of the humidity sensor label is fully compatible with inexpensive, reel-to-reel processing technologies, thus enabling low cost production.

    Thin and well-defined MFI type molecular sieve films were grown on a range of ATR crystals by employing a seeding method. The type of ATR crystal does not influence film morphology. FTIR spectroscopy was used to evaluate the coated ATR crystals as sensor probes. These novel sensor probes could be used to detect low concentrations of organic molecules in a gas flow.

    Assessing kinetics of surface adsorption-desorption of gas molecules via electrical measurements2016In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 223, p. 791-798Article in journal (Refereed)
    Abstract [en]

    Gas sensing represents a grand research and application field. Owing to their unique structure of single-atom/molecule thickness, the emerging two-dimensional (2D) semiconductors are anticipated to display ultrahigh sensitivity capable of detecting minute changes in surface charge. To support the vast variety of gas sensing applications for domestic gases and environmental control, rapid and reliable quantitative analysis of measurement results based on established sensing mechanism and kinetics is essential. The present work uses graphene-based 2D sensors as a model system to establish the analytical capability for assessing the adsorption-desorption kinetics of gas molecules via electrical characterization. By linking the electrical current in graphene to the surface coverage of gas molecules and by incorporating the non-steady-state initial conditions for adsorption and desorption, an analytical model is established. Important kinetic parameters including activation energy, equilibrium coverage and adsorption-desorption time constants are obtained. The model can also facilitate real-world applications in gas sensing.

    Using a MISiCFET device as a cold start sensor2003In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 63, no 1-3, p. 295-303Article in journal (Refereed)
    Abstract [en]

    As a consequence of the formation of water droplets in the car engine at cold start, the fragile ZrO2 λ sensor cannot be heated until the engine is sufficiently warm. A possibility to shorten the time before closed loop λ control would decrease the exhaust emission. As a solution to this problem, the metal insulator silicon carbide field effect transistor (MISiCFET) sensor, which presumably is more thermo shock resistant than the ZrO2 sensor, could be used at cold start. The requirements for a cold start sensor are, among others, sensitivity to λ (air to fuel ratio) close to stochiometry, selectivity to λ and high speed of response. In this communication, the possibility of using the MISiCFET sensor at cold start is treated. The sensor consists of a SiC based MOSFET device with a buried channel design and a catalytic gate metal of 10 nm TaSix and 100 nm Pt. The response depends linearly on λ at 500 °C. The sensitivity of the device has been tested both in artificial atmospheres and in an engine. Two-level factorial designed experiments showed a high selectivity to λ compared to other gases such as CO, hydrocarbons, NOx and H2. The response time was found to be <10 ms at 500 °C when changing from an oxidizing to a reducing atmosphere. The MISiCFET sensor response showed interesting differences in λ stairs when the λ-value was varied by changing the oxygen, hydrogen or CO concentration. The results show that the MISiCFET sensor is a promising choice as a future cold start sensor.

    Abstract [en]

    An AlN thin film electro-acoustic resonator has been fabricated employing a reactive sputtering process for the deposition of an AlN thin film with inclined c-axis for excitation of the shear mode for operation in liquid media. The main objective is to investigate the efficiency of the micro-fluidic channel system integrated in the silicon wafer underneath the AlN resonator. A comparative study between the shear mode thin film bulk acoustic resonator (FBAR) and a quartz crystal microbalance (QCM) using a competitive antibody–antigen association process for detection of drug molecules is presented.

    Abstract [en]

    A shear mode thin film bulk acoustic resonator (FBAR) operating in liquid media together with a microfluidic transport system is presented. The resonator has been fabricated utilizing a recently developed reactive sputter-deposition process for AlN thin films with inclined c-axis relative to the surface normal with a mean tilt of around 30°. The resonator has a resonance frequency of around 1.2 GHz and a Q value in water of around 150. Sensor operation in water and glycerol solutions is characterized. Theoretical analysis of the sensor operation under viscous load as well as of the sensitivity and stability in general is presented. The theoretical predictions are compared with experimental measurements. The results demonstrate clearly the potential of FBAR biosensors for the fabrication of highly sensitive low cost biosensors, bioanalytical tools as well as for liquid sensing in general.

    An electronic tongue in the dairy industry2005In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 111, p. 299-304Article in journal (Refereed)
    Abstract [en]

    The concept of electronic tongues or taste sensors has developed rapidly during recent years due to their large potential. They are based on electrochemical sensors combined with multivariate data analysis. Voltammetric electronic tongues have proven valuable in many applications. Due to their ruggedness and simplicity, they have been found especially suitable for on-line monitoring of industrial processes. A voltammetric electronic tongue, specially designed for use in the dairy industry is described. It consisted of four working electrodes (gold, platinum, rhodium and stainless steel), embedded in PEEK (TM). It was mounted in a housing of stainless steel, which was inserted in the process line for direct on-line measurements. The voltammetric electronic tongue was used to follow different sources of milk coming into the process and to monitor the cleaning process. (c) 2005 Elsevier B.V. All rights reserved.

    The details of a recently demonstrated possibility of making two-dimensional response maps of a gas mixture are discussed. It is described how maps of work-function changes due to the interaction between molecules like ethanol and ammonia and thin catalytic metal films as gates on field-effect structures can be created with a scanning light-pulse technique. Simple image processing is shown to enhance the differences in the response patterns created by different molecules.

    Revisiting the factors influencing gold electrodes prepared using cyclic voltammetry2019In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 283, p. 146-153Article in journal (Refereed)
    Abstract [en]

    Gold is widely used as the electrode material in different chemi- and biosensing applications while cyclic voltammetry (CV) in sulfuric acid solutions is a commonly employed method for gold surface preparation and characterization. However, as shown herein, chloride leakage from the Ag/AgCl/sat. KCl reference electrode and platinum dissolution from the platinum counter electrode can severely compromise the reproducibility and hence the reliability of the prepared gold electrodes. The aim of this work is to obtain a comprehensive understanding of the separate and interdependent effects of the aforementioned factors on the voltammetric behavior of microfabricated polycrystalline gold electrodes. It is shown that the leakage of chloride gives rise to etching of both the gold working and the platinum counter electrodes and that the chloride concentration has a strong influence on the ratio between the obtained gold and platinum concentrations in the electrolyte. The dissolved gold and platinum are then re-deposited on the gold electrode on the cathodic voltammetric scan, changing the structure and properties of the electrode. It is also demonstrated that the changes in the properties of the gold electrode are determined by the ratio between the co-deposited platinum and gold rather than the absolute amount of platinum deposited on the gold electrode. In addition, the chloride and sulfate adsorption behavior on the gold electrode is carefully investigated. It is proposed that redox peaks due to the formation ofthe corresponding Au(I) complexes can be seen in the double layer region of the voltammogram. The results show that the chloride leakage from the reference electrode needs to be carefully controlled and that platinum counter electrodes should be avoided when developing gold sensing electrodes. The present comprehensive understanding of the electrochemical performance of gold electrodes prepared using CV should be of significant importance in conjunction with both fundamental investigations and practical applications.

    Red turn-on fluorescent phenazine-cyanine chemodosimeters for cyanide anion in aqueous solution and its application for cell imaging2014In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 203, p. 833-847Article in journal (Refereed)
    Abstract [en]

    Two chemodosimeters PDMI and PMI for cyanide detection were designed and synthesized based onphenazinecyanine dyes with N-methyl indolium group as receptor unit. According to the specific reactivity of indolium C-N+ bond against cyanide anion, both of them featured high sensitivity with detectionlimit of 1.4 mu M and 200 nM, respectively, and high selectivity against other anions. The quenching effecton phenazine-cyanine fluorophore by strong intramolecular charge transfer (ICT) from phenazine donorto indolium receptor made both PDMI and PMI non-emissive at the original state. After addition ofcyanide, the ICT effect decreased and vanished leading to dramatic " off-on" fluorescence enhancement. PDMI which proceeded bilateral electrophilic reaction toward cyanide anion provided an emission signal at 580 nm in HEPES buffer with naked-eye detectable color change. Probe PMI utilized an unreactiveformyl group instead of one reactive N-methyl indolium group as the electron-withdrawing component. Due to the unilateral recognition process for cyanide the ICT orientation of PMI was redirectedthus exhibited fluorescence enhancement with maximum emission at 630 nm. Meanwhile, PMI wasapplied for monitoring intracellular cyanide in Hela cells and proved to achieve "off-on" fluorescentsignal confirmed by confocal laser scanning microscopic imaging.

    Monitoring uniform and localised corrosion by a radiofrequency sensing method2018In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 257, p. 988-992Article in journal (Refereed)
    Abstract [en]

    A new method for atmospheric corrosion monitoring based on the variation of radiofrequency (RF) wave propagation in a resonator during its corrosion is presented. The ability of the proposed sensor to differentiate between uniform and localized corrosion mechanisms is demonstrated by considering two identical open stub microstrip resonators produced in zinc and aluminum materials, respectively. For that purpose, experimental characterization of electromagnetic wave propagation in the resonators and simulations are compared. The proposed sensitive resonator should therefore be considered as the key element of new corrosion mimetic sensors.

    Fundamental basis of electromagnetic wave propagation in a zinc microstrip lines during its corrosion2016In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 223, p. 352-358Article in journal (Refereed)
    Abstract [en]

    A new method for corrosion monitoring based on the change of the radiofrequency (RF) wave propagation in a microstrip line during its corrosion is presented. For that purpose, the microstrip line is produced in the same metal as the mechanical structure under monitoring. Zinc material is considered in the study since it allows an investigation of uniform as well as localized corrosion when chloride is used. Experimental data and simulations results provide fundamental basis on the sensing mechanisms of the method and evidence the possibility to detect the created corrosion species and to distinguish between localized and uniform corrosion processes. As the consequence, the proposed method should be considered as promising and reliable tool for corrosion monitoring of several materials exposed to various environments

    A reference-less semiconductor ion sensor2018In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 254, p. 102-109Article in journal (Refereed)
    Abstract [en]

    Ion sensing represents a grand research field with tremendous challenges and ample opportunities. A proper operation of ion sensors demands a robust reference electrode (RE), but on-chip integration of a conventional liquid-filled RE is incompatible with semiconductor technology for manufacturing ion-sensitive field-effect transistors as electronic sensors. Here, we demonstrate a reference-less semiconductor ion sensor, RELESIS, that integrates an interdigitated electrode (IDE) with a field-effect transistor. As a constant solution potential is no longer necessary, the use of RELESIS eliminates the need of any RE in ion sensing. The evaluated IDE comprises two intertwined metallic combs, each being covered with a specific sensing layer. One of the combs is connected to the transistor for readout while another is biased with a voltage signal source. Our extensive measurement results with pH sensing confirm that the sensitivity of RELESIS is exclusively determined by the sensitivity difference of the two sensing layers. By eliminating bulky REs, the RELESIS may find myriad ion-sensing applications owing to its miniaturisability, integrability, flexibility and cost advantages.

    Modelling and Characterization of Novel Reference-Less Semiconductor Ion Sensor for pH Sensing2019In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 281, p. 60-71Article in journal (Refereed)
    Abstract [en]

    A SPICE macromodel is developed for a novel reference-less semiconductor ion sensor (RELESIS), which has been proposed to eliminate the use of reference electrode in the field effect based sensor detection. The working principle of the RELESIS, previously validated by a prototype device via pH sensing, is featured by non-constant bulk solution potential, which distincts itself from any conventional ion sensitive field effect transistor. Simulations are performed here using the macromodel and the results fit well with the experimental data. The proposed SPICE macromodel can be used to predict the behavior of the RELESIS and carry out performance optimizations for the RELESIS to be used in various applications.

    An impedance model for the low-frequency noise originating from the dynamic hydrogen ion reactivity at the solid/liquid interface2017In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 254, p. 363-369Article in journal (Refereed)
    Abstract [en]

    Understanding the dynamics of hydrogen ion reactivity at the solid/liquid interface is of paramount importance for applications involving ion sensing in electrolytes. However, the correlation of this interfacial process to noise generation is poorly characterized. Here, the relationship is unveiled by characterizing the interfacial process with impedance spectroscopy assisted by a dedicated electrochemical impedance model. The model incorporates both thermodynamic and kinetic properties of the amphoteric hydrogen ion site-binding reactions with the surface OH groups. It further takes into consideration the distributed nature of the characteristic energy of the binding sites. The simulated impedance matches the experimental data better with an energy distribution of the kinetic parameters than with that of the thermodynamic ones. Since the potentiometric low-frequency noise (LFN) originating from the solid/liquid interface correlates excellently with the real part of its electrochemical impedance spectrum, this work establishes a method for evaluating sensing surface quality aimed at mitigating LFN.

    Schiff base modified α-cyanostilbene derivative with aggregation-induced emission enhancement characteristics for Hg2+ detection2014In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 202, p. 209-216Article in journal (Refereed)
    Abstract [en]

    A Schiff base functionalized α-cyanostilbene derivative (TS) has been synthesized via a simple and straightforward method and characterized by FT-IR, 1H NMR, 13C NMR and mass spectra. TS possessed excellent AIEE properties and exhibited turn-on fluorescent responses to Hg2+. The results of UV-vis and fluorescence titration experiments revealed that TS was selective and sensitive to Hg2+ in pure THF and aqueous environment. The coordination of TS and Hg2+ ions generated TS-Hg complex locked the dancing molecule because of the flexible chain in the middle of the molecule and the complex was lower soluble induced formation of large aggregates that further limited the non-radiative relaxation channel enhanced emission after adding Hg2+ ions in aqueous solution, which had been confirmed by 1H NMR and dynamic light scattering (DLS). © 2014 Published by Elsevier Inc.

    Real time optical immunosensing with flow-through porous alumina membranes2014In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 202, p. 834-839Article in journal (Refereed)
    Abstract [en]

    Through the presentation of analytical data from bioassay experiments, measured by polarimetry, we demonstrate for the first time a real time immunoassay within a free standing macroporous alumina membrane. The 200 nm nominal pore diameter of the membrane enables flow-through, thereby providing an ideal fluidic platform for the targeted delivery of analytes to bioreceptors immobilized on the pore walls, enabling fast sensing response times and the use of small sample volumes (<100 μL). For the immunoassay, the pore walls were first coated with the functional copolymer, copoly(DMA-NAS) using a novel coupling process, before immobilization of the allergen protein, β-lactoglobulin, by spotting. The immuno-assay then proceeded with the binding of the primary and secondary antibody cognates, rabbit anti-β-lactoglobulin and anti-rabbit IgG respectively. Through the use of streptavidin coated quantum dots as refractive index signal enhancers, a noise floor for individual measurements of 3.7 ng/mL (25 pM) was obtained, with an overall statistical, or formal assay LOD of 33.7 ng/mL (225 pM), for total assay time below 1 h.

    Bioinspired design of a polymer-based biohybrid sensor interface2017In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 251, p. 674-682Article in journal (Refereed)
    Abstract [en]

    The key step in the construction of efficient and selective analytical separations or sensors is the design of the recognition interface. Biomimicry of the recognition features typically found in biological molecules, using amino acids, peptides and nucleic acids, provides plausible opportunities to integrate biological molecules or their active sites into a synthetic polymeric backbone. Given the basic role of functional amino acids in biorecognition, we focused on the synthesis of polymerizable amino acid derivatives and their incorporation into a polymer-based biohybrid interface to construct generic bioinspired analytical tools. We also utilized polyvinyl alcohol (PVA) as a sacrificial polymer to adjust the porosity of these biohybrid interfaces. The surface morphologies of the interfaces on gold electrodes were characterized by using scanning electron (SEM) and atomic force (AFM) microscopies. The electrochemical behavior of the polymeric films was systematically investigated using differential pulse voltammetry (DPV) to demonstrate the high affinity of the biohybrid interfaces for Cu(II) ions. The presence of macropores also significantly improved the recognition performance of the interfaces while enhancing interactions between the target [Cu(II) ions] and the functional groups. As a final step, we showed the applicability of the proposed analytical platform to create a Cu(II) ion-mediated supramolecular self-assembly on a quartz crystal microbalance (QCM) electrode surface in real time.
