Nanoscale ‘Pins’ Enhance SERS

Facebook X LinkedIn Email
Lynn M. Savage

Surface-enhanced Raman spectroscopy (SERS) is still a young technique, but it shows promise for elemental and chemical analysis in the semiconductor and biology fields, among others. It has been well established that using silver or gold nanoscale particles increases the sensitivity of the technique, but doing so requires mixing them with the substance to be analyzed — not always easy or convenient. A scanning electron microscope image shows the basic structure of several “nanopins” set among a larger array. The pins could replace silver and gold nanoparticles in surface-enhanced Raman...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.
    surface-enhanced raman spectroscopy
    Surface-enhanced Raman spectroscopy (SERS) is an analytical technique that combines the principles of Raman spectroscopy with the enhancement provided by nanostructured metallic surfaces. Raman spectroscopy is a method used to study vibrational, rotational, and other low-frequency modes in a system by measuring the inelastic scattering of monochromatic light, typically from a laser source. SERS enhances the Raman signal by many orders of magnitude, enabling the detection and identification of...
