Au(iii)-promoted polyaniline gold nanospheres with electrocatalytic recycling of self-produced reactants for signal amplification†
Abstract
A novel and redox-active nanocatalyst, Au(III)-promoted polyaniline gold nanosphere (GPANG), was designed as the nanolabel for highly efficient electrochemical immunoassay of human IgG by coupling with electrocatalytic recycling of self-produced reactants.
