Abstract

Un dispositivo (1) para detectar la energía generada mediante la desintegración no radiativa en un analito o un complejo o derivado del analito (2, 11) al irradiar con radiación electromagnética que comprende una fuente de radiación (6) adaptada para generar una serie de pulsos de radiación electromagnética, un transductor que tiene un elemento piroeléctrico o piezoeléctrico (3) y electrodos (4, 5) que es capaz de transducir la energía generada por el analito o un complejo o derivado del analito (2, 11) en una señal eléctrica, al menos un reactivo (2, 12) proximal a la superficie del transductor (3); teniendo el reactivo (2, 12) un sitio de unión que es capaz de unirse con el analito o el complejo o el derivado del analito (2, 11), un pocillo (9) para contener un líquido (10) que tiene el analito o un complejo o derivado del analito (2, 11) disuelto o suspendido en el mismo en contacto con el transductor (3), un detector (7) que es capaz de detectar la señal eléctrica generada por el transductor (3), y un controlador (8) para controlar la fuente de luz (6) y el detector (7), donde el detector (7) está adaptado para determinar el tiempo de retardo entre cada pulso de radiación electromagnética desde la fuente de radiación (6) y la generación de la señal eléctrica y donde el detector (7) está colocado para detectar solamente la señal eléctrica generada por el transductor (3) hasta un tiempo de retardo seleccionado para distinguir la concentración del analito o de un complejo o derivado del analito (2, 11) a diferentes distancias desde la superficie del transductor (3).
