QDs Boost Protein Pinpointing in Cancer Cells

Facebook X LinkedIn Email
SEATTLE, March 20, 2013 — Understanding a single cell at its molecular level could better aid in the diagnosis and treatment of cancer. The development of a quantum dot color-coding method that illuminates 100 biomarkers in a single cell could do just that, boosting the ability to pinpoint proteins in cancer cells. The technique, developed by researchers at the University of Washington, provides a tenfold increase from the current research standard, analyzing the color patterns of individual cells from cultures or tissue biopsies to determine why a cell will or will not become cancerous. “Discovering...Read full article

    quantum dots
    A quantum dot is a nanoscale semiconductor structure, typically composed of materials like cadmium selenide or indium arsenide, that exhibits unique quantum mechanical properties. These properties arise from the confinement of electrons within the dot, leading to discrete energy levels, or "quantization" of energy, similar to the behavior of individual atoms or molecules. Quantum dots have a size on the order of a few nanometers and can emit or absorb photons (light) with precise wavelengths,...
