Abstract

A novel hemin/phytic acid doped polyaniline (PA-PANI) hydrogel composite was prepared through a simple chemical and self-assembly method, which was modified onto electrode for electrochemical detection of H2O2 released from living cells. It showed good analytical performance with high sensitivity, selectivity and a rapid response for the analysis of H2O2 in the range of 2 to 102 μM, with the detection limit of 1.2 μM. The favorable results mainly originated from both the high conductivity of PA-PANI hydrogel and its network structure preventing hemin from self-dimerization to provide active catalytic species. Furthermore, PA-PANI with good biocompatibility allowed living cells to adhere and resulted in a short diffusion distance between H2O2 released from cells and electrode.
