Featured researches published by Shengjun Tian.


Chemical Communications | 2003

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

Shengjun Tian; Jianyun Liu; Tao Zhu; Wolfgang Knoll

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.
