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 . Technique uses microscopic beads that bind to diseased cells in samples . 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 less than 45 minutes and scientists it could allow people to test for cancer in their own homes .
