This Research Unit established in 2014 but makes use of the long tradition of the Institute of Cell Biology, Histology and Embryology (head: Univ. Prof. Dr. Gottfried Dohr) in electron microscopy. We aim to use and establish state of the art techniques in electron microscopy to further our scientific projects. Current projects are mainly in neuroscience, for example a current FWF project (PI: Gerd Leitinger) striving to understand the iron metabolism in the brain. But we also aim to detect how nanoparticles can pass natural barriers, in cooperation with Ruth Prassl, Eleonore Fröhlich, and Eva Roblegg, and Ivana Vinkovic-Vrcek.
