We’ve seen health-focused smartphones before that can read all kinds of measurements, including stress levels and blood pressure, but researchers at the University of Houston’s College of Engineering claim that mobiles could also be capable of diagnosing disease. The team are developing a diagnostic system that works simply by attaching a $20 (£12) lens to a smartphone. Diagnosing disease relies on being able to spot chemical interactions between the virus or bacteria and a molecule that will bond with only that one thing, such as an antibody. In order to spot these interactions, the team have developed a slide on which the reactions can occur that can be examined using only a smartphone’s camera and flash, with a lens attached to it.
