    Título: “Shedding light on metal interactions with biomolecules”.

    Resumo: Synchrotron-based X-ray absorption spectroscopy (XAS) is a powerful technique for probing thelocal structure and electronic environment around a specific atom and can be applied on mattersin any physical state. Absorption of X-rays subsequently leads to fluorescence emission, which is the basis of another technique: X-ray fluorescence microscopy (XFM). These methods have diverse applications, from defining the coordination sphere around metal ions in metalloproteins, to obtaining elemental distribution maps inside cells.

    Two examples of such applications have been selected for this lecture, where XAS has been used to structurally characterize the reaction products of two antitumor active complexes, Rh2(CH3COO)4, and fac-[Re(bipyridine)(CO)3(H2O)](CF3SO)3, with sulfur-containing biomolecules, monitoring their cellular localization using XFM.

    Ministrante: Dr. Farideh Jalilehvand (University of Calgary, Canadá).
