(EN) METALLIC NANOSTRUCTURES ADAPTED FOR ELECTROMAGNETIC FIELD ENHANCEMENT
(FR) NANOSTRUCTURES METALLIQUES CONÇUES POUR AMELIORER UN CHAMP ELECTROMAGNETIQUE
Abstract
(EN)
The disclosure relates to metallic nanophotonic crescent structures, or 'nanocrescent SERS probes,' that enhance detectable signals to facilitate molecular detections. More particularly, the nanocrescent SERS probes of the disclosure possess specialized geometries, including an edge surrounding the opening that is capable of enhancing local electromagnetic fields. Nanosystems utilizing such structures are particularly useful in the medical field for detecting rare molecular targets, biomolecular cellular imaging, and in molecular medicine.

L'invention concerne des structures nanophotoniques métalliques en forme de croissant, ou des 'sondes SERS (spectroscopie laser de l'effet Raman exalté de surface) en nanocroissant', permettant d'améliorer des signaux détectables pour faciliter des détection moléculaires. En particulier, les sondes SERS en nanocroissant de l'invention présentent des géométries spécifiques, comprenant un bord entourant l'ouverture, ce qui permet d'améliorer des champs électromagnétiques locaux. Des nanosystèmes faisant appel à ces structures sont particulièrement utiles dans le domaine médical pour détecter des cibles moléculaires rares, pour une imagerie cellulaire biomoléculaire, et en médecine moléculaire.
