Abstract [en]

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.
