Chemically specific sulfur imaging of brain tissue. Bright field image (a) shows white matter (blue asterisk) and grey matter (red asterisk). (b) Corresponding sulfur micro-XAS spectra are shown in matching colours. Imaging was performed at incident energies of: (c) 2154 eV for phosphorus, (d) 2473.3 eV for low oxidation state sulfur, thiols and di­sulfides, (e) 2481 eV for sulfonic acids and (f) 2482.6 eV for sulfates. Scale bar = 300 µm.
