A new, highly sensitive chemical sensor uses protein nanowires

Scientists report that they have developed bioelectronic ammonia gas sensors that are among the most sensitive ever made. It uses electric-charge-conducting protein nanowires derived from the bacterium Geobacter to provide biomaterials for electrical devices. They grow hair-like protein filaments that work as nanoscale ''wires'' to transfer charges for their nourishment and to communicate with other bacteria.
