CA 2453430

The invention relates to a sensor for the in vivo measurement of an analyte, comprising a plurality of particles of suitable size such that when implanted in the body of a mammal the particles can be ingested by macrophages and transported away from the site of implantation, each particle containing the components of an assay having a readout which is an optical signal detectable transdermally by external optical means, and either each particles being contained within a biodegradable material preventing ingestion by the macrophages, or each particle being non-biodegradable. The invention relates to a process for the detection of an analyte using such a sensor, comprising implantation of the sensor into the skin of a mammal, transdermal detection of analyte using external optical means, degradation of the biodegradable material, ingestion of the particles by macrophages, and removal of the particles from the site of implantation by macrophages.

L'invention concerne un capteur destiné à la mesure in vivo d'un analyte. Ce capteur comprend une pluralité de particules de taille adéquate telles que lorsqu'elles sont implantées dans le corps d'un mammifère, ces particules peuvent être ingérées par des macrophages et transportées loin du site d'implantation, chaque particule contenant les composantes d'un dosage possédant un indicateur qui est un signal optique pouvant être détecté à travers le derme à l'aide d'un moyen optique extérieur, et soit chaque particule est contenue dans un matériau biodégradable empêchant l'ingestion par les macrophages, soit chaque particule est non biodégradable. L'invention concerne également un procédé permettant de détecter un analyte à l'aide d'un tel capteur, qui comprend l'implantation du capteur dans la peau d'un mammifère, la détection transdermique de l'analyte à l'aide d'un moyen optique extérieur, la dégradation du matériau biodégradable, l'ingestion des particules par des macrophages, et l'élimination des particules du site d'implantation par des macrophages.
