The tobacco plants are harvested and chopped up to extract the structures.<br /> <br /> According to the Francis Research Group at the Department of Chemistry UC Berkeley, lead by Professor Matt Francis, "The protein coat of the tobacco mosaic virus (TMV) has been explored extensively for the construction of nanoscale architectures. This protein can be produced in very high yield through E. coli expression and self-assembles into light harvesting rods that are much like those assembled from the wild-type protein." Tobacco mosaic virus has a rod like appearance and causes characteristic patterns or mottling and discolouration of tobacco leaves.<br /> <br /> Electricity has not yet been harvested using this method, and unlike silicon, this manufacturing process of solar cells is not quite efficient and the cells would not last as long as silicon, but it could act as a transportable, cheap and temporary biodegradable power source.<br /> <br /> Copyright ©2010 IDTechEx<br /> Captcha: Please Enter Code : * Time Zone: * Select the time zone Vocabularies Newsletter: Domain: Show summary in full view Input format Filtered HTML Web page addresses and e-mail addresses turn into links automatically.
