Abstract:In this work, an enzymatic liquid-gated field-effect-transistor sensor based on chemically reduced graphene oxide film was develop for determination of acetylthiocholine in aqueous conditions. The device was designed with interdigitated electrode configuration and then manufactured by combining lithography and chemical vapor deposition techniques in clean room. Graphene oxide material (prepared by Hummer method) was chemically reduced using a strong reducing agent hydrazine, and then drop-casted onto the chann… Show more
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.
