Electronic nanostructures made from natural amino acids are attractive because of their
relatively low cost, facile processing and absence of toxicity,,. However, most materials
derived from natural amino acids are electronically insulating,,,,,. Here, we report metallic-
like conductivity in films of the bacterium Geobacter sulfurreducens and also in pilin
nanofilaments (known as microbial nanowires,) extracted from these bacteria. These
materials have electronic conductivities of∼ 5 mS cm− 1, which are comparable to those of …
