    Smartphone-Based System Tests for Infectious Diseases, Sends Results to Doctor

    Article obtained from Photonics RSS Feed.

    Engineers at the University of Cincinnati (UC) have created a tiny portable lab that plugs into a smartphone. The lab, which is about the size of a credit card, can diagnose infectious diseases such as coronavirus, malaria, HIV, or Lyme. It can also track hormones related to anxiety or depression. The patient puts a single-use plastic lab chip into his or her mouth and the saliva on the chip is tested. The device automatically transmits test results to a doctor’s office through a custom app developed at UC.

    The lab chip uses natural capillary action to draw a sample down a capillary flow assay composed of two microchannels. The functionally designed microchannels, along with adequate hydrophilicity, produce a sequential flow of…
