'Tornado' lab-on-a-chip technology with micro tweezers to detect dangerous viruses, biological contaminants

Purdue University researchers have developed a new class of optical nanotweezers that can trap and detect biomolecules, viruses and DNA more rapidly. The technology can also use light to promptly detect cancer or improve the production of medications, an important step forward as nearly half of Americans have used at least one prescription drug within the past month.
