Internal Senior Fellow
July 2008 - October 2010
Gerald Urban is a Full Professor of Sensors at the Department of Microsystems engineering at the University Freiburg. He is a director of the Freiburger Materials Research Centre and elected member of the academic senate of the university. His research interests are dedicated to the development of chemo- and biosensor systems for clinical and system-biological applications.
Gerald Urban studied technical physics at the TU Vienna and was employed at the neurosurgical department of the AKH Vienna afterwards. Subsequently he worked on his PhD thesis at the Department of Electrical Engineering at the TU Vienna. In 1985 he founded together with colleagues the company OSC in Cleveland, Ohio and Vienna. In 1986 and 1987 he was a post-doc at the neurophysiological department in Münster, Germany. From 1990 till 2002 he was scientific director of the Ludwig Boltzmann Institute of Biomedical Microengineering in Vienna. He finished his habilitation in 1994 and became a full professor at the university Freiburg in 1997. From 1999 to 2002 he was dean of the Faculty for Applied Science at the University Freiburg.
He is series editor of “Chemo- and Biosensors” for the SPRINGER publishing house
His awards include the Stefan Schuy price for biomedical technology, the AVL List price, a best poster price and the Hoechst price.
He is author of more than 70 publications and 43 patents
Systems biology needs the knowledge of a variety of metabolic pathways which can be investigated using micro- and nanobiosensor systems. To achieve this goal electrochemical microsensor arrays have to be modified to achieve highest selectivity and biocompatibility. This will be done by using nanohybrid composites consisting of aligned carbon nanotubes decorated with metallic and semiconducting nanoparticles and biological sensing components to optimize the heterogonous electrocatalytic behaviour. Additionally functional polymers have to be introduced enhancing the catalytic and transport properties as well as cell compatibility for biological applications.
Such sensor systems will be implemented in a microfluidic to create new analytical systems as well as microsystems facilitating stem cell differentiation. This will be done in close cooperation with the external fellow Manz.
