Reactive Oxygen and Nitrogen Species – “Nanosweeper” for Rheumatoid Arthritis Theranostics by Macrophage Reprogramming

Excessive reactive oxygen and nitrogen species (RONS) accumulation in joints are significant variables that affect the course of rheumatoid arthritis (RA). Scavenging of RONS to remodel macrophage homeostasis is a potentially powerful treatment for RA. Here, a visualized "nanosweeper" by functionalizing ultrasmall Gd/Fe
