Sensor, aparato y procedimiento para la determinación de la concentración de solutos en disoluciones

Abstract

[ES] Sensor, aparato y procedimiento para la determinación de la concentración de solutos en disoluciones. En este documento se describe un sensor. un aparato y procedimiento que permite un análisis directo de fluidos para determinar cantidades de solutos en disoluciones. Para ello se puede hacer uso de transductores con estructuras monocapa o multicapa (como puede ser una estructura fotónica planar en forma de microcavidad de Bragg) porosa birrefringente. El Procedimiento de la invención presenta dos posibles configuraciones; una primera configuración en la cual se tiene un sensor que es cristal fotónico en una estructura microfluídica que comprende dos ventanas transparentes, llevándose a cabo la toma de datos en modo de transmisión, y una segunda configuración en las cual el cristal fotónico que actúa como sensor se encuentra ubicado en un extremo de una fibra óptica, procediéndose a la toma de datos en el modo de reflexión.

[EN] The document describes a sensor, apparatus and method for the direct analysis of fluids in order to determine a concentration of solutes in solutions, such as the concentration of glucose in aqueous solutions. Transducers with porous birefringent monolayer or multilayer structures (such as a planar photonic structure in the form of a Bragg microcavity) may be used as sensors. The method of the invention can be performed in two possible implementations; a first one, wherein the sensor (2) is a photonic crystal in a microfluidic device (1) which comprises two transparent windows, data being retrieved in transmission mode and a second one, wherein the photonic crystal sensor is located on the tip of an optical fiber, data being retrieved in reflection mode.
