Biosensing with NV-centers in optically trapped nanodiamonds (Invited Paper)

Kirstine Berg-Sørensen is associate professor in biological physics at the Technical University of Denmark. Her earliest research experience dealt with quantum mechanical and semi-classical models of laser cooled atoms and the physics of such laser cooled atoms while in 1999 she changed direction to biological physics. This change was kick-started by a grant from the Danish Research Agencies to initiate the first optical tweezers activity in Denmark, at the Niels Bohr Institute, University of Copenhagen. Within biological physics, she has been interested in analysis and models of data from single molecule experiments, both in in vitro and in vivo systems, with main emphasis on experiments conducted using optical tweezers, optical traps in microfluidic systems and also micro-particle-velocimetry measurements. Most recently, she focuses on experimental work to couple biophysics and optical trapping in biological systems with quantum sensing by means of color centers in diamonds.
