Abstract:The preparation and property studies of long-wavelength-emitting carbon dots (CDs) nanozymes with multifunctions like multienzyme activity nanozymes, antibacterial, and antioxidation have promising prospects in biochemical detection and clinical fields. This paper reports the fast preparation of dual enzyme-like active yellow-green carbon quantum dots (4-ASA/Gd-CDs) through a one-step hydrothermal route with the rare-earth element Gd doping, 4-aminosalicylic acid (4-ASA), and polyethyleneimine (PEI) as raw mat… 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.
