SERS Advances Disease Diagnosis

Facebook X LinkedIn Email
DURHAM, N.C., March 3, 2011 — Scientists at Duke University have developed a new noninvasive optical technique that uses a laser to peer into the genetic material of cells, enabling the detection of early-stage cancer and other diseases. The method uses metallic nanoparticles dubbed “molecular sentinels” to advance the technique known as surface-enhanced Raman scattering, or SERS. Leading the Duke team was Tuan Vo-Dinh, who has pioneered the practical application of SERS over the past 20 years. He is the R. Eugene and Susie E. Goodson Distinguished Professor of Biomedical Engineering and director of The...Read full article

    laser-induced fluorescence
    Laser-induced fluorescence (LIF) is a spectroscopic technique that involves using a laser to excite molecules or atoms, leading to their emission of fluorescence light. This technique is widely used in scientific research, analytical chemistry, and various fields for studying the composition and properties of substances. Key features of laser-induced fluorescence include: Laser excitation: A high-energy laser beam is used to selectively excite specific molecules or atoms in a sample. The...
    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 scattering
    Surface-enhanced Raman scattering (SERS) is a powerful analytical technique that enhances the Raman scattering signal of molecules adsorbed on or near certain nanostructured surfaces. Raman scattering is a process in which light interacts with molecular vibrations, providing a fingerprint-like spectrum that can be used to identify and characterize chemical compounds. SERS significantly amplifies the Raman signal, making it more sensitive and allowing for the detection of molecules at very low...
