  • ADSORBABLE POLYMERIC SURFACE-ENHANCED RAMAN SPECTROSCOPY SUBSTRATES AND THE FABRICATION PROCESS
    Publication number: 20220228993
    Abstract: The present invention related to surface-enhanced Raman spectroscopy (SERS) substrates that are adsorbable and flexible comprises a polymeric base with detailed specific embossed structures on the surface and noble metal nanoparticles coated on the polymeric base, wherein the capillary effect is exhibited by the nanometer-sized rough features embedded in the micrometer-sized stripe patterns on the surface of the embossed polymeric base, the distances between the coated noble metal nanoparticles are between 50-200 nm to allow for sufficient number of hot spots for high Raman signal enhancement, the ridge width of the embossed stripe pattern is between 15-80 pm, and the distance between the ridges of the embossed stripe pattern is 0.04-0.14 mm.
