Quantum and classical phenomena in biology and nanophysics

Welcome to the QuantBioLab website

The Quantum Biology and Nanophysics research group was established at the University of Southern Denmark (SDU) in October 2013 and is headed by Ilia A. Solov'yov.

Our research interests cover a broad range of questions on theory of biomolecules and smart inorganic materials. Of particular interest are those biological processes that trigger energy conversion into forms that are usable for chemical transformations and are quantum mechanical in nature. Such processes involve chemical reactions, light absorption, formation of excited electronic states, transfer of excitation energy, and transfer of electrons and protons in chemical processes. Equally challenging are problems in nanophysics which focus on potential applications in nano- technology, material science and medicine.

Birds have an intriguing sense that allows them to navigate in the Earth's magnetic field. This sense is likely tied to the photoreceptor cryptochrome arising in the retina. However, the biophysical mechanism of cryptochrome activation and signaling is still poorly understood. A recent study proposed a theoretical analysis method for identifying cryptochrome's signaling reactions involving comparison of measured and calculated reaction kinetics.
