Engineers at the University of Cincinnati created something really unique. They created a portable chemistry lab that plugs into your phone, and can diagnose things like the coronavirus and malaria. It’s only about the size of a credit card. The patient simply puts a single-use plastic lab chip into his or her mouth then plugs that into a slot in the box to test the saliva. The device automatically transmits results to the patient’s doctor through a custom app UC created for nearly instant results.
