Abstract:An amperometric biosensor for glucose determination was developed using a carbon paste electrode (CPE) modified with cellulose acetate (CA)/glucose oxidase (GOx) bilayer membrane through the electrostatic interaction between them. The CA membrane was used as matrix for enzyme immobilization via microencapsulation technique, is enzyme placed between two membranes. CA/GOx membrane was attached to CPE surface containing ferrocene (Fc). By using proposed amperometric biosensor, glucose concentration was determined… 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.
