Welcome to the Bio- and Nano-Photonics research group
Head of the Laboratory
Prof. Dr. Alexander Rohrbach
University of Freiburg
Living cells are fascinating microsystems. Therefore we develop novel techniques for laser optical microscopy and optical force based applications, to investigate the biophysics of living cells and of bio-mimetic systems based on their nano-mechanics and thermal fluctuations.
