  • Method for preparing a surface enhanced Raman spectroscopy particle
    Patent number: 10215702
    Abstract: There is provided a method of preparing a surface enhanced Raman spectroscopy (SERS) particle comprising the step of encapsulating a plurality of Raman molecules on the surface of a metallic core with a biocompatible protective shell at an elevated temperature selected to decrease the encapsulation time by more than one-fold relative to an encapsulation performed at 20° C.
    Type: Grant
    Filed: July 30, 2012
    Date of Patent: February 26, 2019
    Assignee: Agency for Science, Technology and Research

  • Surface Enhanced Raman Spectroscopy (SERS) compounds and methods of their preparation
    Patent number: 9006458
    Abstract: A compound for detecting an analyte using Surface Enhanced Raman Spectroscopy (SERS) and a method of forming the compound is provided. The compound has Formula I: wherein W is selected from the group consisting of an optionally substituted aryl group and an optionally substituted heteroaryl group; each Y independently is NR1R2, wherein R1 and R2 are independently selected from the group consisting of H and C1-C6 alkyl, or R1 and R2 combine to form together with the nitrogen to which they are attached a heterocyclic group with 4 to 5 carbon atoms, is used to denote a single or a double bond, and Z is NH, NH2, NH—(C?O)—(CH2)n—SH, wherein n=1 to 10, or or a tautomer or stereoisomer thereof, or a salt thereof. A method and device for detecting an analyte using Surface Enhanced Raman Spectroscopy (SERS) is also provided.
