In recent years, researchers have developed nanoparticles for a host of medical applications, from drug delivery to imaging of tumors. Now, in a Nature Nanotechnology paper published online July 26, 2009, a team at the University of Washington has reported a nanostructure that combines two such particles in a single package: a sort of Swiss army knife for nanomedicine. “Each type of nanostructure has its strengths and weaknesses in biomedical imaging and therapeutics,” said Xiaohu Gao, lead author of the paper (Yongdong Jin is the other author) and a UW assistant professor of...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.
    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,...
