| Scientists can select from the rich choice of materials that nature provides to make devices that can convert electrical energy to light energy, like lasers or light emitting diodes – or to make devices that convert light energy from the sun, to electrical energy. We could potentially make much more efficient devices , if we could control the nanostructure (not the atomic structure) of the material to add the right combination of semiconductors, metals and insulators. Biological structures can possess both the nanoscale structure that can serve as a template for building materials, and also strongly specific binding of materials to those templates. The big challenge is to link biological materials with what we usually think of as "non-biological" materials, like metals or semiconductors. I will discuss a technique that can provide that linkage: a discovery tool that will identify compatible biological-non biological material pairs. This provides the starting point for a new way of constructing non biological materials from the nanoscale, allowing creative three dimensional design of new materials and electronic and optical devices. |
