Preferred Label : Quantum Dot;
NCIt synonyms : Quantum Dots;
NCIt definition : Nanometer-sized semiconductor particles, made of cadmium selenide (CdSe), cadmium
sulfide (CdS) or cadmium telluride (CdTe) with an inert polymer coating. The semiconductor
material used for the core is chosen based upon the emission wavelength range being
targeted: CdS for UV-blue, CdSe for the bulk of the visible spectrum, and CdTe for
far red and near-infrared. The size of the particle determines the exact color of
a given quantum dot. The polymer coating protects cells from cadmium toxicity but
also facilitates the attachment of a variety of targeting molecules, including monoclonal
antibodies directed to tumor-specific biomarkers. Because of their small size, quantum
dots can function as cell- and even molecule-specific markers that will not interfere
with the normal cellular functions.;
