LOS ANGELES, April 11 (UPI) -- U.S. researchers say a device can turn a cellphone camera into a diagnostic tool for checking for contaminated water or monitoring HIV-positive patients.
Engineers at the University of California, Los Angeles, described how a device fitted to a cellphone allows its camera to capture images from a fluorescent microscope and flow cytometer used to count and characterize cells in a liquid sample, making it possible for medical personnel in areas with limited resources to easily run diagnostic tests for the human immunodeficiency virus and other diseases.
