Bacterial Extracellular Electron Conduits Exhibit Spin-Selective Transport via CISS Effect
Multiheme cytochromes (MtrF and OmcA) on the surface of Shewanella oneidensis MR-1 — which enable long-distance (>10 nm) extracellular electron transfer to solid minerals and electrodes — have been demonstrated to exhibit spin-selective electron transport. Using magnetic conductive probe AFM, Hall v…
A Unified Phase-Space Topology Explains Bacterial Depletion and Alignment in Shear Flows
This paper presents a first-principles analytical hydrodynamic model for bacterial transport in low-Reynolds-number flows, resolving a long-standing gap in active matter theory. The central result is that shear-induced bacterial depletion near walls and flow-alignment are not independent phenomena b…
