A laser-induced TiO2-decorated graphene photoelectrode for sensitive photoelectrochemical biosensing†
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.
