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.

Journal Article Physical chemistry chemical physics : PCCP · May 2026 Electron bifurcation reactions separate electron pairs into high and low potential pools, and these reactions are central to the bioenergetics of living systems. Here, we used kinetic analysis and machine learning to analyze a diverse set of structural and ...

Journal Article The journal of physical chemistry letters · May 2026 Chiral phonons, with their intrinsic angular momentum, are potential contributors to the chiral induced spin selectivity (CISS) effect, which can induce significant spin polarization in the absence of strong spin-orbit coupling. An open question is how non ... Full text CiteSources 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 CiteRecent Grants
