Division of Bionanophotonics

The Division of Bionanophotonics is engaged in fundamental and applied nanophotonics and biophotonics studies at the international research frontier. The Division hosts two principal investigators / group leaders, Professor Mikael Käll (head of division) and Docent 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 and Chalmers Materials Analysis Laboratory. We also have a number in house experimental facilities, mainly various optical microscopy and spectroscopy setups. We are always intrested in talented and enthusiastic MSc, PhD or post doc candidates - just give us a call or e-mail Mikael and/or Timur!

Steven's project deals with measuring the temperature in plasmonic nanoparticles, so-called anti-Stokes spectroscopy. The new instrument will be placed in Chalmers Material Analysis Laboratory (CMAL) and will be available to all users at Chalmers and Gothenburg University on equal terms. Congatulations Steve!! A picture of the prize certificate can be seen here.
