Nanocatalytic Medicine: Photothermo‐Promoted Nanocatalysis Combined with H2S‐Mediated Respiration Inhibition for Efficient Cancer Therapy (Adv. Funct. Mater. 8/2021)

In article number 2007991, Yu Luo, Hangrong Chen, and co-workers report a novel kind of polyvinyl pyrrolidone modified multifunctional iron sulfide nanoparticles (Fe1−xS-PVP NPs), which can in situ generate highly toxic hydroxyl radicals under a tumor environment and simultaneously produce H2S gas to suppress the activity of the enzyme cytochrome c oxidase in cancer cells. The external stimulation of 808 nm near-infrared irradiation will further facilitate this process.
