CA 2628056

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.

La présente invention concerne des procédés de modification fonctionnelle d'une surface polymère en vue d'un dépôt ultérieur de particules et/ou de pellicules métalliques, laquelle surface polymère est modifiée selon un procédé consistant à augmenter le nombre de groupes fonctionnels hydroxyde et/ou amine, ce qui permet d'obtenir une surface polymère activée en vue du dépôt de particules métalliques pour former un dispositif de détection de fluorescence. Le dispositif peut être utilisé pour obtenir une fluorescence renforcée par un métal de fluorophores positionnés au-dessus des particules métalliques pouvant directement intervenir dans des applications de diagnostic ou de détection de fluorescence renforcée par un métal.
