The Biophysics and Biophotonics group at Umeå University is located at the Department of Physics. We mainly develop and apply photonic techniques to study biological processes. For over 15 years, we have developed optical tweezers that are used for micromanipulation, force spectroscopy, and Raman spectroscopy. We also build software for tracking, image-processing, microfluidic systems using 3D-printing technology and digital holographic microscopy imaging.

More information and details regarding our instruments and research can be found here.
