Figure 6From: Distribution of silver in rats following 28 days of repeated oral exposure to silver nanoparticles or silver acetate Energy dispersive x-ray emission spectra of granules in the ileum. Energy dispersive x-ray emission spectra of granules in lysosomes of silver nanoparticle and silver acetate exposed rats (red line) and corresponding background spectra (black line), i.e. spectra of surrounding tissue containing no visible granules (unstained sections). The transmission electron micrographs show the analyzed granule containing area.Back to article page
