Title
(EN) REDUCTION OF IN VIVO ANALYTE SIGNAL DEGRADATION USING MULTIPLE METALS
(FR) RÉDUCTION DE LA DÉGRADATION IN VIVO D'UN SIGNAL D'ANALYTE À L'AIDE DE MULTIPLES MÉTAUX
Abstract
(EN)
A sensor (e.g., an optical sensor) that may be implanted within a living animal (e.g., a human) and may be used to measure an analyte (e.g., glucose or oxygen) in a medium (e.g., interstitial fluid, blood, or intraperitoneal fluid) within the animal. The sensor may include a sensor housing, an analyte indicator covering at least a portion of the sensor housing, and a multiple metal protective system including multiple metals incorporated in and/or in close proximity to a surface of the analyte indicator that reduce deterioration of the analyte indicator.
(FR)
La présente invention concerne un capteur (par exemple, un capteur optique) qui peut être implanté dans un animal vivant (par exemple, un humain) et qui peut être utilisé pour mesurer un analyte (par exemple, le glucose ou l'oxygène) dans un milieu (par exemple, un fluide interstitiel, du sang ou un fluide intrapéritonéal) dans l'animal. Le capteur peut comprendre un boîtier de capteur, un indicateur d'analyte recouvrant au moins une partie du boîtier de capteur, et un système de protection à multiples métaux comprenant de multiples métaux incorporés dans une surface et/ou à proximité immédiate d'une surface de l'indicateur d'analyte qui réduisent la détérioration de l'indicateur d'analyte.
