Microbiologists at the University of Massachusetts Amherst have found a way to make electrical wires that are thousands of times thinner than a human hair.*
The secret? The "microbial na**wires," or little hair-like protein filaments, or pili, produced by genetically modified soil bacteria, Geobacter sulfurreducens. Researchers manipulated the bacteria to spin out very fine but highly conductive wires composed of natural ami** acids.*
They replaced two naturally occurring ami** acids in the Geobacter bacteria with tryptophan, (yes, the tryptophan that makes you sleepy on Thanksgiving (http://www.nytimes.com/2015/11/26/science/**-the-tryptophan-in-turkey-wont-make-you-sleepy.html)), and found that it was 2,000 times more conductive (https://www.umass.edu/news******/article/%E2%80%98green%E2%80%99-electronic-materials-produced). They also became smaller and more durable, with a diameter of 1.5 na**meters (rough 60,000 times thinner than a human hair).* Read more...
