Tiny biomolecular chambers called nanopores that can be selectively heated may help doctors diagnose disease more effectively if recent research by a team at the National Institute of Standards and Technology (NIST), Wheaton College, and Virginia Commonwealth University (VCU) proves effective. Though the findings* may be years away from application in the clinic, they may one day improve doctors’ ability to search the bloodstream quickly for indicators of disease -- a longstanding goal of medical research.
