Switchable Nanostructures Made with DNA-BIOMEDICAL NEWS
Opens possibility of responsive ‘nanomachines’ for applications in energy and data storage
Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have found a new way to use a synthetic form of DNA to control the assembly of nanoparticles — this time resulting in switchable, three-dimensional and small-cluster structures that might be useful, for example, as biosensors, in solar cells, and as new materials for data storage. The work is described in Nature Nanotechnology, published online December 20, 2009.
