Luminescent Gold Nanoparticles with Efficient Renal Clearance

Abstract

Going to waste: Renal clearance of 2 nm glutathione-coated luminescent gold nanoparticles (GS-AuNPs) was more than 10 to 100 times better than that of the similarly sized nonluminescent AuNPs coated by bis(p-sulfonatophenyl)phenylphosphine and cysteine. Urinary excretion of the particles was imaged with X-ray computed tomography (see picture of a mouse after injection of GS-AuNPs) and luminescence techniques in real time.
