摘要：

A facile approach for the fabrication of nonenzymatic hydrogen peroxide sensor based on conducting polyaniline (PANI) nanofibers functionalized with gold nanoparticles (AuNPs) was demonstrated. With the introduction of thioglycolic acid (TA) dopant, small and well-dispersed AuNPs were immobilized on the PANI nanofibers. Due to the stabilization by the TA linked with PANI, the growth and aggregation of AuNPs were restrained, leading to the formation of AuNPs with smaller size and well dispersion. These novel nanomaterials exhibit fast response, broad linear range, good reproducibility and highly sensitive for the detection of H2O2.
