Engineers at the University of California San Diego and the University of California Berkeley have created light-based technology that can detect biological substances with a molecular mass more than two orders of magnitude smaller than previously possible. The advance was made possible by building a device that shrinks light while exploiting mathematical singularities known as exceptional points (EPs).
