A method of detecting at least one analyte in extra-cellular spaces includes the step of inserting a microprobe through the stratum corneum toward the stratum basale of the skin of a subject into extra-cellular spaces containing interstitial fluid having at least one analyte to be detected, said microprobe having a diameter at its tip no larger than approximately 10-50 microns. The method further includes optically testing for a predetermined analyte in the extra-cellular space adjacent the distal end of the microprobe without drawing a sample of the interstitial fluid. Preferably the microprobe body includes a sensor layer covering the distal optical tip of the microprobe body, the sensor layer being adapted to interact with a predetermined analyte to be detected in the interstitial fluid, and an optical detector responsive to interaction of the sensor layer with the predetermined analyte to signal detection of said predetermined analyte.

L'invention concerne une méthode destinée à la détection d'au moins un analyte dans des espaces extracellulaires, consistant à insérer une microsonde à travers la couche cornée vers la couche basale de la peau d'un sujet dans des espaces extracellulaires contenant du fluide interstitiel renfermant au moins un analyte à détecter, ladite microsonde ayant un diamètre à sa pointe inférieur à environ 10-50 microns. Cette méthode consiste également à tester optiquement un analyte prédéterminé dans un espace extracellulaire adjacent à l'extrémité distale de la microsonde sans prélever un échantillon du fluide interstitiel. De préférence, le corps de la microsonde comprend une couche de détection recouvrant la pointe optique distale du corps de la microsonde, la couche de détection étant conçue pour interagir avec un analyte prédéterminé à détecter dans le fluide interstitiel, et un détecteur optique sensible à l'interaction entre la couche de détection et l'analyte prédéterminé, destiné à signaler la détection dudit analyte prédéterminé.
