Probe Emits Light in Living, Unharmed Cells

Facebook X LinkedIn Email
STANFORD, Calif., Feb. 14, 2013 — A new class of light-emitting probes small enough to be injected into individual cells without harming them could provide new ways of exploring the dynamics of living cells. The Stanford University engineers are the first to demonstrate that sophisticated engineered light resonators can be inserted inside cells without damaging them. Their nanobeam — only a few microns in length and just a few hundred nanometers in width and thickness — looks similar to a piece from an old erector set with holes through the beams that act like a nanoscale hall of mirrors, focusing and...Read full article

    gallium arsenide
    Gallium arsenide (GaAs) is a compound semiconductor material composed of gallium (Ga) and arsenic (As). It belongs to the III-V group of semiconductors and has a zincblende crystal structure. GaAs is widely used in various electronic and optoelectronic devices due to its unique properties. Direct bandgap: GaAs has a direct bandgap, which allows for efficient absorption and emission of photons. This property makes it suitable for optoelectronic applications such as light-emitting diodes...
    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,...
