Revolutionary Material: Microbial Nanowires

The picture above is of the microbe Geobacter (red) expressing electrically conductive nanowires. Such natural nanowires can be mass produced from inexpensive, renewable feedstocks with low energy costs compared to chemical synthesis with toxic chemicals and high energy requirements. Microbiologist Derek Lovley and his team at the University of Massachusetts Amherst report that they have discovered a new type of natural wire produced by bacteria that could greatly accelerate the researchers’ goal of developing sustainable “green” conducting materials for the electronics industry.
