Photothermal therapy using traditional conversion agent was limited by the complexity of cancer. It was urgent to find a new efficient and inoffensive photothermal conversion agent. Herein, we synthesized W18O49, a non-invasive and efficient photothermal conversion agent for photothermal therapy application. This work revealed that the morphology of W18O49 was changed for photothermal therapy by poly ethylene glycol (PEG) modification. Meanwhile, with 808 nm irradiation, W18O49@PEG nanoparticles could covert laser energy into hyperthermia, which could further induce cancer cells ablation.
NIR-II responsive PEGylated MoO2 nanocrystals with LSPR were prepared and efficient photothermal and photodynamic enhancement performance and mechanisms were investigated.
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.
