From: In vivo observation of gold nanoparticles in the central nervous system of Blaberus discoidalis
TEM of treated and untreated brains. Transmission light image of (a) nAuNPs treated dissected cockroach brain and (b) control. Darker tissue is a sign of nanoparticles. A clear difference can be observed in the treated tissue (a) while the untreated (b) shows no difference in the tissue. Fluorescent image of (c) nAuNPs trated and (d) untreated samples. The lower window shows the fluorescent intensity at the location of the yellow line on the upper windows.
