Abstract:In this work, we have reported use of anthocyanin capped gold nanoparticles (Ant@Au NPs)‐incorporated colorimetric urease test for rapid, sensitive and economic detection of Helicobacter pylori (H. pylori). This test containing Ant@Au NPs, urea, sodium phosphate buffer (PBS) and sodium azide (NaN3) was prepared at pH 5 with red solution owing to dispersity of Ant@Au NPs, urease enzyme secreted from H. pylori cause production of ammonia (NH3) via hydrolysis of urea, then which makes reaction environment alkalin… 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.
