Microbial Nanowires Go the Distance
The discovery of a fundamental, previously unknown property of microbial nanowires in the bacterium Geobacter sulfurreducens that allows electron transport across long distances could revolutionize nanotechnology and bioelectronics with practical applications for environmental cleanup and renewable energy sources. Lead microbiologist Derek Lovley with physicist Mark Tuominen and UMass Amherst colleagues, say networks of bacterial filaments, known as microbial nanowires because they conduct electrons along their length, can move charges as efficiently as synthetic organic metallic nanostructures, and they do it over remarkable distances, thousands of times the bacterium’s length.
