Electrifying Nature

Welcome to the research group of Nadav Amdursky for the study of charge transfer processes.

Biological charge transfer processes, such as the ones in the respiratory system, are the basis for our life, where proteins are Nature’s main choice for the translocation of charges. As such, we as scientists have the obligation of understanding the fundamentals of these processes. In our research group we explore various types of charge transfer properties mainly across peptides and proteins, while distinguishing between electron and proton transfer.

In order to study the transfer properties we attach a charge donor to the biological material (peptide, protein or membrane), and we follow the charge transfer in-vitro mainly by fast spectroscopy. The group is equipped with state-of-the-art laser system that is capable to detect fast charge transfer processed on the time order of few femtoseconds.

The ability of biological molecules to mediate charges has resulted in the formation of the field of bioelectronics, where biomolecules are probed for their ability to mediate electronic conduction. In our group we use different types of bioelectronic device configurations from the nm-scale to the macroscale, to probe the ability of biomaterials to conduct both electrons and protons while applying an electric field.

One of the end goals of our group is to design protein-based biomaterials with tunable electronic properties for the use of tissue engineering.
