Abstract

ESTE BIOCAPTADOR COMPRENDE POR LO MENOS UNA MEMBRANA (8) EN LA QUE ESTA INMOVILIZADO UN ENZIMA QUE CATALIZA LA TRANSFORMACION DE UN SUBSTRATO QUE INTERVIENE EN EL METABOLISMO CUTANEO, MEDIOS PARA DETECTAR Y MEDIR UN FENOMENO PROVOCADO POR ESTA TRANSFORMACION, REPRESENTATIVO DE LA CONCENTRACION DE SUBSTRATO A DOSIFICAR PUESTO EN CONTACTO CON LA MEMBRANA (8) Y UNA CELULA DE MEDIDA (13), CUYA ZONA DE PARED ESTA FORMADA POR LA MEMBRANA (8), Y QUE SE PUEDE OBTURAR CUANDO MIDE, POR UNA ZONA DE REVESTIMIENTO CUTANEO (15), ESTANDO ASOCIADA LA CELULA (13) A MEDIOS PARA HACER CIRCULAR UN LIQUIDO PARA PONER EN DISOLUCION EL SUBSTRATO A DOSIFICAR. PARA LA MEDIDA, SE APLICA EL BIOCAPTADOR SOBRE LA PIEL, SE INYECTA TAMPON EN LA CELULA Y UNA VEZ LLENA ESTA, SE EFECTUA LA DETECCION Y LA MEDIDA, Y DESPUES SE HACE CIRCULAR DE NUEVO TAMPON PARA ELIMINAR EL SUBSTRATO SOLUBILIZADO. ESTE CICLO DE MEDIDA SE PUEDE REPETIR SIN RETIRAR EL ELECTRODO (1). APLICACION A LA DOSIS DE L-LACTATO CUTANEO POR UN ELECTRODO DECLARK ASOCIADO A UNA MEMBRANA DE L-LACTATO OXIDASA.
