Synthesis and characterization of organo-soluble aniline oligomer-based electroactive doped with gold nanoparticles, and application to electrochemical sensing of ascorbic acid

Synthesis and characterization of organo-soluble aniline oligomer-based electroactive doped with gold nanoparticles (EPI-4G) modified carbon paste electrode (CPE) carried out best in sensing AA at lower oxidative potential with good sensitivity, relative low detection limit, broad linear dynamic range and best selectivity for a tertiary mixture of AA/UA/DA compared to the other tested electrodes.206
