May 27, 2009... Spire Corporation, a provider of turnkey solar factories, reports that it has been granted a patent for silicon or gallium arsenide photovoltaic devices ranging in size from 50 nm to about 5 microns. The patent covers the design of the tiny solar cells and the method of their fabrication. The patent describes one of several possible applications which is to inject nanophotovoltaic devices into diseased tissue, e.g., cancerous tissue. Penetrating light activates these cells. In theory this would generating an electric fields in the tissue, causing a disruption of the cancerous cells.

“This is an extension of our solar energy technology into biotherapeutics. Functionalized nanophotovoltaic devices can go to cancerous cells in the body and when exposed to tissue penetrating light, may provide sufficient electrical energy to destroy the cells. We are continuing to exploit this technology in our research and development activities,” Roger G. Little, Chairman and CEO of Spire Corporations, and co-inventor, said. Company News Release
