Polyaniline doped with modified gold nanoparticles and its electrochemical properties in neutral aqueous Tsolution

Doping polyaniline with COO– -modified gold nanoparticles by forming stable layer-by-layer multilayer films can shift its electroactivity to neutral pH. The films can electrocatalyze the oxidation of NADH and offer potential applications in other fields, e.g., optoelectronics or biosensing.
