Chem Commun (Camb). 2019 Apr 23;55(34):4945-4948. doi: 10.1039/c9cc00889f.

Abstract

Herein, direct-laser-writing of TiO2-decorated graphene on indium-tin oxide glass was demonstrated to fabricate a unique photoelectrode with a rapid and stable photoelectrochemical response under visible light; this photoelectrode was then applied in a photoelectrochemical enzymatic biosensor for the sensitive detection of an acetylcholinesterase inhibitor.
