Programming Biology - Tunable Microbial Nanowires

Nature Nanotechnolgy reports:<blockquote>the conductivity of the biofilm can be tuned by regulating gene expression, and also by varying the gate voltage in a transistor configuration. The conductivity of the nanofilaments has a temperature dependence similar to that of a disordered metal, and the conductivity could be increased by processing.</blockquote> [gallery link=”file” columns=”2”]
