Abstract

Sistema para la medida de la concentración de una sustancia de ensayo que comprende: un sensor (10) que dispone de un cuerpo de polímero (22) que comprende fluoróforo, presentando dicho fluoróforo una actividad de fluorescencia que se ve alterada de forma medible en relación con la concentración de la sustancia de ensayo y medios de transporte de luz (12) para transportar luz hasta y desde el fluoróforo; un fuente de luz de bombeo (40) que, al activarse, aplica luz a los medios de transporte de luz (44, 48, 12) para activar el fluoróforo; un detector (54) para detectar luz emitida por el fluoróforo del cuerpo de polímero (22) y generar una señal en respuesta a la misma; un dispositivo de análisis (76, 92, 94, 96) para analizar la señal generada por el detector, y calcular a partir de esa señal la concentración de sustancia de ensayo detectada por el sensor (10); caracterizado por el hecho de que el detector (54) funciona para detectar el cambio transitorio en la luz emitida por el fluoróforo simultáneamente con la fuente de emisión de luz de bombeo (40) que funciona para aplicar luz a los medios de transporte de luz (44, 48, 12).
