CA 2757007

This invention relates to an optical sensor element comprising a photonic crystal constituted by a membrane of a chosen transparent material, the membrane being provided with a number of defined openings in a chosen pattern, the pattern being adapted to provide resonance at a chosen wavelength or range of wavelengths, wherein said openings are provided with a reactive material acting as a receptor for a chosen type of molecules, e.g. proteins, the presence of which alters the resonance and/or scattering conditions in the sensor element thus altering the amount of light propagating out of the membrane plane.

La présente invention concerne un élément formant capteur optique comprenant un cristal photonique constitué d'une membrane d'un matériau transparent choisi, la membrane étant pourvue de plusieurs ouvertures définies selon un motif choisi, le motif étant conçu pour produire une résonance à une longueur d'onde ou dans une plage de longueurs d'ondes choisies. Dans cet élément, lesdites ouvertures sont pourvues d'un matériau réactif agissant comme un récepteur pour un type choisi de molécules, par exemple des protéines, dont la présence modifie la résonance et/ou les conditions de dispersion dans l'élément formant capteur, modifiant ainsi la quantité de lumière propagée à partir du plan de la membrane.
