Nanoenhanced biosensor detects single proteins

Facebook X LinkedIn Email
The microcavity biosensor that set a record by detecting the smallest single virus in solution has reached a new breakthrough: detecting a single label-free cancer marker protein. The achievement shatters the previous record and sets a new benchmark for the most sensitive limit of detection – and could significantly advance early disease diagnostics. In 2012, Stephen Arnold of Polytechnic Institute of New York University (NYU-Poly) and colleagues at Fordham University and New York City College of Technology developed a novel microcavity biosensor treated with plasmonic gold...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
