  • Condensed Matter Seminar: "The Physics of Electron-Conducting Microbial Nanowires"

    Room A4, DRL

    Mark Tuominen , University of Massachusetts

    This talk will discuss the experimental investigations of “natural organic metals” -- nanowires produced from amino acids by a common soil bacteria, Geobacter sulfurreducens. These protein nanofilaments, pili, extend outside of the cell for long distances and tangle into a network. Electron conductivity is observed in bacterial biofilms, and also in networks of pili extracted from the bacteria.

  • Condensed Matter Seminar: "Single-molecule force spectroscopy: Theory meets experiment"

    Room A4, DRL22

    Olga Dudko, U.C. San Diego

    Single-molecule biophysical tools are making it possible to measure the response of individual biomolecules to external force – in real time and with unprecedented resolution – revealing information that is typically lost when studied though traditional “bulk” methods. I will present a general analytical theory of force-induced molecular transitions. The theory is based on Kramers picture of diffusive barrier crossing and on a generalization of this picture to many dimensions.
