Bionanophotonics

The Division of Bionanophotonics is engaged in fundamental and applied nanophotonics and biophotonics studies at the international research frontier. The Division hosts four principal investigators / group leaders, Mikael Käll (head of division), Alexander Dmitriev, Andreas Dahlin and Timur Shegai. Many of the current projects deals with plasmons in metal nanostructures and their interactions with molecules and other nanoobjects. The group is truly international (currently 10 nationalities represented) and consists of MSc and PhD students, post docs and senior scientists. We do experiments, theory and computer simulations and we are  heavy users of Chalmers Nanofabrication Laboratory, Chalmers Materials Analysis Laboratory and Chalmers Center for Computational Science and Engineering. We also have a number in house experimental facilities, mainly various optical microscopy and spectroscopy set ups.
