With inexpensive materials, iPhone becomes imaging device

UC Davis researchers have turned an iPhone into a medical device capable of performing detailed microscopy. By attaching an inexpensive ball lens to the iPhone's existing camera, the scientists created a device powerful enough to examine blood cells. Additionally, the camera can take pictures of the images the souped-up lens sees. Researcher say the inexpensive device could help physicians in rural and developing areas that lack high-tech lab equipment diagnose blood diseases. Article
