Biological nanowires carry electricity thanks to special amino acids

In nature, the bacterium Geobacter sulfurreducens uses these nanowires, called pili, to transport electrons to remote iron particles or other microbes, but the benefits of these wires can also be harnessed by humans for use in fuel cells or bioelectronics. A new study reveals that a core of aromatic amino acids are required to turn these hair-like appendages into functioning electron-carrying biological wires.
