Iron oxides are naturally occurring compounds, and several methods have been developed for generating iron oxide nanoparticles (IONPs) with a focus on precisely modulating their size and physicochemical properties. Facile synthesis approaches, narrow size distribution, ease of surface modification, tunable magnetic properties, and size-dependent elimination from blood circulation, make IONPs attractive for use in different biomedical applications. This review describes the use of IONPs for application in tissue repair and regeneration with a focus on neural and musculoskeletal tissues.
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.
