Nanotech gadget could diagnose any disease
16 January 2009
This article is about a microchip that is able to detect a whole range of medical diseases has been developed by chemists in the U.S. Personally, i think this is a wonderful idea. Now, people can possibly get their medical diagnosis at the touch of a button, so to speak. However, I don't think that this product would really get off the ground. The main reason that I dont think that it would market well is because it would be quite pricey. On the otehr hand, hypochondriacs may reep the benefits of having this device sitting at their bedside table. Otherwise, this product seems ingenious. It would be very handy for person battling various illnesses. Would I buy it? no, i wouldn't. Is it a good idea? without doubt
