Digital diffraction diagnosis or D3 could be used to detect cancerous cells in blood or tissue samples and even detect infections from HIV and Ebola . The researchers are now working on a new version of the device that will use an optical fiber instead of copper wires for data transmission. These clumps of beads change how light is scattered through the sample and can be detected using the camera on a smartphone like an iPhone . Results from the £1.20 ( $ 1.80 ) test are received under 45 minutes and scientists it could allow people to test for cancer in their own homes .
