제목 Biological Functionalization of the Surface on Polypyrrole Nanotubes with Heparin for the Detection of Protein
초록 Carboxylated polypyrrole (CPPy) nanotubes were fabricated by the chemical copolymerization of pyrrole and pyrrole-3-carboxylic acid(P3CA), and applied as biosensor for thrombin protein. CPPy nanotubes were anchored on an amine-functionalized Au interdigitated microelectrode substrate and the conductivity values (dI/dV) were found to be around 10-3S. A field-effect-transistor(FET) sensor platform was constructed with CPPy nanotubes. Heparin/CPPy nanotubes showed specific and fast response upon exposure to thrombin protein.
