A new and simple method was developed to produce gelatin nanoparticles of $ 30-40 nm for use as carriers for drug release applications. The nanoparticles were uniform in size and well dispersed. An anticancer drug, 5-fluorouracil, was encapsulated with an efficiency as high as 85%. The nanoparticles showed sustained release of 5-fluorouracil, and release rates varied with amount of crosslinking in the nanoparticles.
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.
