Overview
Dr. Beratan is developing theoretical approaches to understand the function of complex molecular and macromolecular systems, including: the molecular underpinnings of energy harvesting and charge transport in biology; the mechanism of solar energy capture and conversion in man-made structures; the nature of charge conductivity in naturally occurring nucleic acids and in synthetic constructs, including the photochemical repair of damaged DNA in extremophiles; CH bond activation by copper oxygenase enzymes; the flow of charge in bacterial appendages on the micrometer length scale; the theoretical foundations for inverse molecular design - the property driven discovery of chemical structures with optimal properties; the exploitation of molecular diversity in the mapping of molecular and materials "space"; the use of infra-red excitation to manipulate electron transport through molecules; the optical signatures of molecular chirality and the influence of chirality on charge transport. Prof. Beratan is affiliated with the Departments of Chemistry, Biochemistry, Physics, as well as Duke's programs in Computational Biology and Bioinformatics, Structural Biology and Biophysics, Nanosciences, and Phononics.

Recent Publications
Sources of non-Arrhenius electron transport in bacterial nanowires.
Journal Article Physical chemistry chemical physics : PCCP · April 2026 Electron transport in biological redox chains typically follows an Arrhenius law, with rates and conductivities that increase with temperature. Surprisingly, bacterial nanowires show anti-Arrhenius transport. We simulated electron transport in a one-dimens ... Full text CiteFrom single step hops to emergent biological phenomena.
Journal Article Journal of inorganic biochemistry · March 2026 Charge transfer and transport are fundamental to chemistry and biochemistry. Since the 1950s, theorists and experimentalists have advanced the field to develop a molecular-level understanding of single-electron/one-step electron transfer, and ongoing studi ...

Journal Article Chemical science · March 2026 Cable bacteria contain electron-transport pathways that are among the longest found in living systems, reaching the centimeter scale. These bacteria have very high electrical conductivities, and the electron- transport mechanism is poorly understood. We pe ... Full text CiteRecent Grants
