摘要
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.
