Abstract

A simple and enzymeless amperometric sensor for the detection of H2O2 based on a new kind of nanomaterial Mo-6 S9-xIx (MoSI) nanowires (NWs) was developed. The construction of the sensing platform was based on strong electrostatic interactions between negatively charged MoSI NWs and positively charged thionin molecules. MoSI NWs act as not only a good substrate for the immobilization of redox mediator thionin, but also a promoter for electrocatalysis of H2O2. The fabricated sensor showed a wide linear range over the concentration of H2O2 from 5 mu M to 2.8 mM with a measurable lowest detection of 0.8 mu M; furthermore, it exhibited good stability and reproducibility.
