title: X-ray absorption spectroscopy of low-molar-mass metallic complexes in pharmacy.
abstract: X-ray absorption spectroscopy provides valuable information on metallic speciation and so has a wide range of applications in bioinorganic systems. In this paper, low-molar-mass metallic complexes as used in pharmaceutical science are focused on. The results of structural studies on metal-based drugs applied as disease treatments, nutritional supplements or tools for diagnostic methods are presented. Then metal speciation (spatial and chemical distribution) in biological samples through micro-XANES imaging experiments are dealt with. Problems arising from the analysis of noisy data collected from these diluted samples are discussed.
