Wow, that happened faster than I thought it would..
Some scientists are now turning Smartphones into handheld tools to diagnose cancer or infectious disease, track treatment progress or check water safety.
Harvard Medical School used a cell phone and a lunch box–size machine to diagnose cancer from tiny pieces of tissue, taken via needle from the abdomens of patients with suspected metastatic cancers. Researchers mixed the samples with antibodies that bound to four known cancer-related proteins. The machine analyzed the samples using nuclear magnetic resonance—measuring levels of the antibody-bound proteins based on their magnetic properties. It then sent the results to the smartphone, which, using an app that the researchers designed, displayed the data. Because doctors don’t need a laptop or desktop, it would be easier for them to assess patients outside the clinic. In comparison, results from more traditional diagnostic methods are typically not available for three days and require more invasive tissue sampling
