The toxicity and biodistribution in vivo of various morphologies of Au nanoparticles (AuNPs) were studied by using KM mice. The quantitative analysis of Au in each tissue of mice was done by using the Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Sphere-shaped AuNPs displayed the best biocompatibility, compared with rod- and cube-shaped of AuNPs, and rod-shaped AuNPs was more toxic than cube-shaped AuNPs. in vivo biodistribution study revealed all AuNPs were preferentially accumulated in organ of liver and spleen. The findings from this study thus revealed that the toxicity and biodistribution in vivo of AuNPs are shape dependent.
