抄録

Simple and robust properties are the important aspects for biosensing chip. We have fabricated Pt and Au interdigitated array electrodes (Pt-Au IDEs) for amperometric biosensor. A spontaneous electrical current generation was observed depending on H₂O₂ concentration. The glucose oxidase (GOx) immobilized Pt-Au IDEs exhibited a glucose sensor action in which H₂O₂ produced by the enzymatic reaction of GOx was detected through Pt-Au IDEs. The phenomenon demonstrated that Pt-Au IDEs can provide a simple amperometric biosensor without an external potential source nor a reference electrode.
