Abstract In order to exploit the applications of polypyrrole (PPy) derivatives in biosensors and bioelectronics, the different immobilization mechanisms of biomolecules onto differently functionalized conducting PPy films are investigated. Pyrrole and pyrrole derivatives with carboxyl and amino groups were copolymerized with ω-(N-pyrrolyl)-octylthiol self- assembled on Au surface by the method of the chemical polymerization to form a layer of ...
