WebJan 2, 2024 · The aim of this study was to investigate the uptake, cytotoxicity, biodistribution and in vivo toxicity of commercially available and well-characterized AuNPs (5 nm, 20 nm and 50 nm) with a specific focus on the size-dependent effects, and to explore their potential mechanisms of toxicity in cancer cells and normal cells. Materials and methods WebTriphenylphosphine monosulfonate (TPPMS) was synthesized by Ahrland’s modified method [13]. To 20 mL of 30 % sulfuric acid at 0 ºC, 10 g (3.8 mmol) of triphenylphosphine were added slowly with stirring. The mixture was slowly heated on a water bath for 2 h and then added to a beaker with 100 g of ice; at
