Researchers from Sandia National Laboratories (Albuqerque, NM USA) are part of a multi-disciplinary team developing a nano-size battery that one day could be implanted in the eye of a patient to power an artificial retina. They are among the recipients of a five-year grant recently awarded by the National Eye Institute of the National Institutes of Health (NIH) to establish a new center, the National Center for Design of Biomimetic Nanoconductors, based at the University of Illinois Urbana-Champaign. The center will develop new nanomedical devices beginning with a class of devices for generating electric power.
