Reduced-silver staining of Drosophila larvae CNS. (a) Optical microscope image. Scale bar: 50 µm. (b) Scanning electron microscopic analysis. X-ray emission spectra were obtained for the 40 µm × 40 µm area indicated in the backscattered electron image shown in the upper-right inset. Emission-line energies of relevant elements are labeled. The aluminium line was from the sample support. Images were obtained using a Hitachi S-3200N scanning electron microscope operating at 20 kV. (c) XAFS spectra of the Au LIII absorption edge. Closed circles: CNS sample; open circles: 20 µm gold-foil standard.
