Abstract

We demonstrate that, with appropriate staining, high-resolution X-ray microscopy can image complicated tissue structures-cerebellum and liver-and resolve large or small amounts of Au nanoparticles in these tissues. Specifically, images of tumor tissue reveal high concentrations of accumulated Au nanoparticles. PEG (poly(ethylene glycol)) coating is quite effective in enhancing this accumulation and significantly modifies the mechanism of uptake by reticuloendothelial system (RES) organs.
