Azurin from Pseudomonas aeruginosa and two mutants where the methionine ligand has been mutated have been studied in order to directly investigate the functional and structural significance of this ligand in the blue copper proteins. Reduction potentials, X-ray absorption fine structure (XAFS), electron paramagnetic resonance (EPR), and optical spectra are obtained in an attempt to provide a di...

S3ve.r oxide (Ag@ and Ago) layers were prepared by lhe anodic oxidation of silver metal in 1M NaOH and investigated in situ with XAFS at grazing incidence. For given glancing angles, x-ray absorption fme structure spectra of the anodic oxides were extracted from these reflectivity data The evaluation of these absorption data yields detailed near range orda structural information about the elect...

About ten different European user groups work on biomedical research projects at the SRXRF/XANES-microprobe beamline L. For this community a dedicated one-day workshop about life science-applications at this beamline was held at HASYLAB on 17.03.2006. The workshop placed emphasis on different aspects of sample preparation techniques, but also general topics like imaging techniques in life scien...
