Fig. 3From: Effects of biologically produced gold nanoparticles: toxicity assessment in different rat organs after intraperitoneal injectionTEM micrographs that were obtained from the biologically produced GNPs. a scale bar = 200 nm and b scale bar = 20 nm. In both micrographs, the nanoparticles had hexagonal shapes with average sizes of about 50 nmBack to article page
