Abstract: Electrical shock The iron-reducing soil bacterium Geobacter sulfurreducens has hair-like protein structures called pili on its surface. These were believed to attach the cell to a substrate. But now a surprise: they also conduct electricity. This suggests a new mechanism for bacterial electron transfer, and raises the prospect of mass production of protein nanowires suitable for nanoelectronic devices.
