Research

Bernd Giese untersucht die molekularen Eigenschaften von Radikalen in chemischen und biologischen Prozessen. Es hat sich gezeigt, dass diese kurzlebigen Moleküle im chemischen Labor gezielt eingesetzt werden können und dass die Natur diese hochreaktiven Radikale insbesondere für kompliziertere Reaktionen verwendet. In Enzymen und der DNA werden diese Radikale häufig durch Elektronentransfer erzeugt, wobei Biopolymere (Proteine und DNA) geeignete Materialien für den Transport von Elektronen darstellen. Solche Prozesse spielen in entscheidenden biologischen Reaktionen eine große Rolle.

Bernd Giese studies the properties of radicals in chemical and biological reactions. It has turned out that one can apply these short-lived molecules in the chemical laboratory, and that nature uses these highly reactive radicals especially to carry out complex reactions. In enzymes and DNA these radicals are often generated by electron transfer, where biopolymers (proteins and DNA) are appropriate materials for electron transfer over long distances. These reactions play important roles in essential biological processes.
