Researchers from the University of Maryland have come up with an interesting new use for the tobacco mosaic virus; significantly increasing the surface area of electrodes. The increase is quite impressive, a 3.6-fold improvement in areal capacitance over a planar equivalent due to the increased surface area created by the nickel oxide coated TMV. Not only does this research offer improvements in supercapacitors it opens up a new area of research which could enhance a wide variety of electrically charged devices. Drop by Nanotechweb for a look at the science behind this.
"Scientists in the US have devised a microfabrication method that uses capillary channels in a photoresist to position nanorods of the tobacco mosaic virus (TMV). The team used the quick and simple new approach to create a supercapacitor with nanostructured electrodes, and the method can be applied to construct many other microdevices requiring high surface areas."
