Plasmonic nanomaterials have been widely used for photothermal therapy (PTT) of cancer, but their recognition specificity remains challenging. We prepared monosaccharide-imprinted gold nanorods (AuNRs) for targeted cancer PTT, using sialic acid (SA) as a representative monosaccharide. The SA-imprinted AuNRs exhibited good specificity, enabling the killing of cancer cells without damaging healthy cells.
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.
