Effect known from solid-state physics discovered in biological systems

A new study with the participation of HYP*MOL spokespersons Georgeta Salvan and Jörg Matysik, the results of which have now been published in the journal Chemical Science, demonstrates a polaron effect in cyanobacteriochromes. It is a light-induced switching process that could be traced in detail over individual sub-process steps, also thanks to innovative sample preparation methods developed by first author Lisa Köhler. Corresponding effects are known primarily from solid-state physics, so that semiconductor physicist Georgeta Salvan played a key role in data interpretation.
