Open the CIPO recordAbstract From the Canadian patent
The present invention relates to methods for functionally modifying a polymeric surface for subsequent deposition of mettalic particles and/or films, wherein the polymeric surface is modified by increasing hydroxyl and/or amine functional groups thereby providing an activated polymeric surface for deposition of metallic particles to form a fluorescence sensing device. The device can be used for metal-enhanced fluorescence of fluorophores positioned above the metallic particles that can be readily applied to diagnostic or sensing applicantions of metal-enhanced fluorescence.
