2D MoS2/glassy carbon based electrochemical sensor for pico-molar detection of hydrogen peroxide and hypochlorous acid

摘要

This study reports the synthesis of a ultra-sensitive biosensor for free radical (hydrogen peroxide) and hypochlorous acid detection at the physiological level and below. The polyacrylonitrile derived glassy carbon electrode was modified with liquid exfoliated 2D MoS2 nanoparticles. Biosensor works for wide range of potential and performs multi-role detection eliminating the use of specific compound dedicated electrodes.
