smartphone blood-clotting test 1

Caption

Researchers at the University of Washington have developed a new blood-clotting test that uses only a single drop of blood and a smartphone vibration motor and camera. The system includes a plastic attachment that holds a tiny cup of blood beneath the phone's camera (shown here). Note: This photo simulates how this system works, and the "blood" shown here is not real.
