Biological nanomaterials

Living bacteria is able to produce semiconducting nanotubes that can be applied in electronics, nanotechnology, as well as other fields of material science.The discovery might help in the creation of new nanoelectronic devices. Scientists named Nosang Myung and Bongyoung Yoo discovered that a bacteria called Shewanella created arsenic-sulfide nanotubes with unique characteristics that resembled those of a metal. These nanotubes had electrical and photoconductive properties. For the first time nanotubes were ceveloped by biological means rather than chemical. The finding might be a great step towards the production of less costly and eco-friendly electronic materials.
