Bacteria Can Form Nanowires

Researchers at the Pacific Northwest National Laboratory (PNNL) have discovered that under certain conditions, some very common bacteria can form nanowires. These bacteria were able to produce nanowires as small as 10 nanometers in diameter, but which can reach hundreds of microns in length. What is interesting here is that these nanowires are electrically conductive ones. This means that bacteria could be used to build microbial fuel cells or bacteria-powered batteries

“Earth appears to be hard-wired,” said Gorby, staff scientist at the Department of Energy’s Pacific Northwest National Laboratory, who documents the seeming ubiquity of electrically conductive microbial life in the July 10 advance online Proceedings of the National Academy of Sciences
