  • SUBSTRATES FOR SURFACE ENHANCED RAMAN SPECTROSCOPY
    Publication number: 20160274031
    Abstract: Methods for fabricating metal nano-particle embedded enhancement substrates used for surface enhanced Raman spectroscopy (SERS) including ion implanting metal nano-particles into the substrate and etching the substrate to partially expose the metal nano-particles. The resulting material is useful as a SERS substrate for detection of molecules adsorbed on it by surface enhanced Raman spectroscopy.
    Type: Application
    Filed: March 16, 2016
    Publication date: September 22, 2016
    Applicant: THE UNIVERSITY OF HOUSTON SYSTEM
    Inventors: Wei-Kan Chu, Dharshana N. Wijesundera, Indrajith Rajapaksa
