A startup called T2 Biosystems is developing a test that uses magnetic nanoparticles to detect blood-borne infections in hours—compared to the days it now takes using conventional lab methods. The company’s first device—about the size of a printer—will target Candida, a fungus that is the third-most-common cause of hospital-acquired infections. The detection system can identify Candida in human blood samples in about two hours. Clinical trials involving samples from actual patients are in the works.
