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 H 2 O 2 concentration. The glucose oxidase (GOx) immobilized Pt-Au IDEs exhibited a glucose sensor action in which H 2 O 2 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
