Thiolsulfinates/Thiolsulfonates formation: X-ray photoelectron spectroscopy (XPS) of oxidized thiols on flat surfaces
Independent thesis Advanced level (degree of Master (One Year)), 30 credits / 45 HE creditsStudent thesis
In order to find another way to fix peptides on surfaces we study the chemical and electro oxidation of a Silicon flat surface after silanization. Traditional experimental setup is used to make the oxidations and Xray photoelectron spectroscope (XPS) is used to analyze the surfaces. We find that chemical oxidation works well but we cannot fix the Alanine molecule on the surface, unlike the electro oxidation which works for peptides fixation. We need to focus on the electro oxidation process, use a more accurate method to analyze the samples and probably used a higher Alanine concentration.
