X-Ray Fluorescence Measurements Identifies and Locates Tattoo Particle Elements in Skin And Lymph No

Caption

μ-XRF mapping identifies and locates tattoo particle elements in skin and lymph node tissue sections. Sections of skin and lymph node tissue from donor 4 were analyzed by means of synchrotron μ-XRF. a) Visible light microscopy (VLM) images of the area mapped by μ-XRF. Tattoo pigments are indicated by a red arrow. b) DAPI staining of adjacent sections showing the cell nuclei. c) μ-XRF maps of P, Ti, Cl and/or Br. For the lymph node, areas of similar size are marked in a) and b). d) Average μ-XRF spectra over the full area displayed in c) * = diffraction peak from sample support; ** = scatter peak of the incoming beam. e) Ti K-edge μ-XANES spectra of skin and lymph node compared to transmission XANES spectra of reference material of rutile, anatase and an 80/20 rutile/anatase mixture calculation.
