چکیده انگلیسی
Herein, a visible light photoelectrochemical (PEC) platform based on polyaniline (PANI) and nanoMoS2 composites as optoelectronic material for glutathione detection without any auxiliary of biomolecules or labeled materials was developed. Firstly, the nanoMoS2 was prepared via a simple ultrasound exfoliation method. The PANI was synthesized by chemical oxidative polymerization method. Then composite of PANI and nanoMoS2 was used to modify gold electrode. It was found that the composite membrane showed excellent PEC properties. And glutathione enhanced the PEC signal greatly. Based on this finding a method for glutathione detection was fabricated. Under the optimum conditions, the linear response of glutathione concentrations ranged from 1.0â¯Ãâ¯10â10 to 1.0â¯Ãâ¯10â4 molâ¯Lâ1 was obtained with a detection limit of 3.1â¯Ãâ¯10â11 mol Lâ1. The relative standard deviation was 2.9% at 2.0â¯Ãâ¯10â9 M (nâ¯=â¯10). This method showed high sensitivity and simpleness which opened up a new promising signal-on PEC platform for future bioassay.
