Transistor-like Behavior of Bacterial Nanowires

The latest issue of Nature Nanotechnology announces ground-breaking results on the conductive properties of networks of bacterial filaments. The discovery that microbial nanowires in the bacterium Geobacter sulfurreducens  provide "metal-like" electron transport across long distances has impact on physics, biology and nanotechnology. This result is the culmination of the thesis work of Nikhil Malvankar, under the supervision of Physics Professor Mark Tuominen and Microbiology Professor Derek Lovley.  ...more
