Facile Synthesis and Characterization of Ag/Ag2S Nanoparticles Enzymatically Grown In Situ and their Application to the Colorimetric Detection of Glucose Oxidase
Abstract:This work describes a simple, fast and reproducible biochemical reaction to modulate the growth of silver/silver sulfide nanoparticles (Ag/Ag 2 S NPs) through the enzymatic activity of the glucose oxidase (GOx). This process occurs in aqueous buffered solutions at room temperature under physiological conditions with participation of inexpensive precursors. Oxidation of 1thio-β-D-glucose is catalyzed by GOx yielding hydrogen sulfide. Direct interaction between silver nitrate and enzymatically produced H 2 S in … 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.
