Abstract: The peroxidase-like functionality of iron oxide (IO) nanoparticles has attracted substantial attention in cancer treatment by reactive oxygen species (ROS) catalytic over-generation. However, the inefficient intracellular ROS generation still hurdles ready-to-use application of IO nanoparticles, attributing to the transient lifetime and limited diffusion distance of ROS. Indeed, excessive ROS generation in mitochondria is desirable to enhance cell death against cancer cells. In this study, we designed zinc-do… Show more
scite is a Brooklyn-based startup 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 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.
