Highly active pyrite nanoenzymes and their self-catalyzed anti-tumor research progress
Time of Update: 2021-04-28
The researchers used first-principles calculation methods to explore the reasons and found that compared with traditional Fe3O4 nanozymes, the covalent bond of pyrite (FeS2) nanozymes when interacting with the substrate H2O2 is shorter, and the surface Contains many gully-like structures, making it more capable of binding to the substrate, so it can catalyze the limited H2O2 at the tumor site, produce a large number of hydroxyl free radicals, and cause bioon.
