Figure 6From: In vivo synthesis of nanomaterials in plants: location of silver nanoparticles and plant metabolismElectron-dense precipitates recovered from leaf parenchymal cell of Brassica juncea and X-ray spectra of elements. Bar corresponds to 1,000 nm. Insets represent enlarged region where X-ray microanalyses have been performed. Bar corresponds to 100 nm. Ag peaks, at 23 keV, were well visible. The presence of C, Os, U and Pb was due to sample preparation, and Cu was due to the grids used as section support.Back to article page
