fergus07 writes "Researchers have detected oral cancer cells using a fiber-optic cable and an off-the-shelf Olympus E-330 camera worth $400. The work by Rice University biomedical engineers and researchers from the University of Texas M.D. Anderson Cancer Center could improve access to diagnostic imaging tools in many parts of the world where these expensive resources are scarce. In the tests, a common fluorescent dye was used to make cell nuclei glow brightly and images were taken using the tip of the fiber-optic bundle attached to the camera. The distorted nuclei, which indicate cancerous and pre-cancerous cells, could then be distinguished on the camera's LCD monitor."
