Abstract
Un dispositivo de muestreo de constituyentes de fluido biológico y de medición de la concentración, comprendiendo dicho dispositivo: (a) una matriz de micro-agujas, teniendo cada micro-aguja una abertura de acceso; (b) una capa de material de gel hidrófilo sobre la matriz; (c) una primera capa de material conductor sobre la capa de material de gel hidrófilo, y (d) una segunda capa de material conductor, en el que la primera capa de material conductor y la segunda capa de material conductor están separadas, en el que se hace que el fluido biológico presente en la abertura de acceso se transfiera al espacio entre la primera y segunda capas de material conductor, caracterizado porque la primera capa de material conductor es porosa y adicionalmente en el que las aberturas de acceso, la capa de material de gel hidrófilo y la primera capa de material conductor proporcionan una ruta de transferencia del constituyente.
