Mihri Ozkan and Cengiz Ozkan have been listening to cancer cells and it could lead to a new treatment for cancer. The two have been applying nanotechnology to “listen” to the subtle singles put off by cancer cells and then using what they hear to apply chemotherapy to only the cancerous cells leaving the health cells alone. With all the work being done in nanotechnology what are you doing in this area? If you aren't investing in these new technology areas your competitors are. As nanotechnology based products come to the market will you still have a competitive product?
