Abstract

Un implante (110) es mostrado para detectar al menos un analito (126) en un fluido corporal, particularmente agua ocular. El implante (110) es diseñado para ser implantado en una capa de tejido y/o una cámara ocular de un paciente y comprende una matriz de hidrogel (110) que contiene al menos un hidrogel (114). El implante posteriormente comprende partículas de sensor (116) que son dispersadas en la matriz de hidrogel (110). Las partículas del sensor (116) tienen al menos una matriz de sensor (120) con un material de matriz de sensor (122) así como al menos un material de sensor (124).
