Step aside, surface-enhanced Raman scattering probes. There’s a new nanoprobe in town, and it can shine 20 times brighter than a conventional probe when swept with an infrared laser. The discovery could lead to better-targeted drug delivery and deeper bioimaging within tissue. The design, developed at Washington University in St. Louis, is based on a novel gold nanoparticle arrangement and Raman reporters – molecules whose jiggling atoms respond to a probe laser by scattering light at characteristic wavelengths. Called Brights – Bilayered Raman-Intense Gold...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.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    raman spectroscopy
    Raman spectroscopy is a technique used in analytical chemistry and physics to study vibrational, rotational, and other low-frequency modes in a system. Named after the Indian physicist Sir C.V. Raman who discovered the phenomenon in 1928, Raman spectroscopy provides information about molecular vibrations by measuring the inelastic scattering of monochromatic light. Here is a breakdown of the process: Incident light: A monochromatic (single wavelength) light, usually from a laser, is...
