Biomarker System Offers Advanced Cancer Detection

Facebook X LinkedIn Email
SINGAPORE, Nov. 21, 2014 — A combined biomarker and drug delivery system could lead to very localized, more effective cancer treatment. Developed by researchers at Nanyang Technological University, the biomarker detects and makes visible tumor cells by lighting up under a near-infrared imaging device. It has also demonstrated the ability to release medications to treat cancer in those exact cells. Coumarin-hemicyanine (CHC1)-modified upconversion nanophosphors, which make up the biomarker, glow under NIR light when tumor cells release a hydrogen sulfide (H2S) signaling agent. “This inorganic-organic...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.
