From single step hops to emergent biological phenomena.

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 studies explore multi-step, multi-electron, and multi-particle transfer and transport. This review highlights studies from our group on electron transfer beyond the one-electron/one-step regime. In particular, we review progress on electron bifurcation reactions, ultra-long range hopping transport in cable bacteria and bacterial nanowires, oxidative damage pathways, and charge transport pathways in nucleic acids. We highlight emerging themes and mechanisms across biological structures, including the roles being discovered for electron-electron correlations, rapid long-range multi-step biological electron transport, unconventional charge transport pathways, and competing charge transfer mechanisms.
