ABSTRACT Translation of nanoparticles (NPs) into clinical practice has been limited by toxic effects
induced by nonspecific accumulation of NPs in healthy organs after systemic administration. The ideal NPs should accumulate in the target site, carry out their function, and then ultimately be eliminated from the body. Here, we show a single-compartment, multifunctional ultrasmall copper sulfide nanodot (CuS ND) that is rapidly cleared from the body. These CuS NDs have a hydrodynamic diameter of
