Abstract

UN METODO PARA FABRICAR ELECTRODOS BIOCOMPATIBLES DE ALTA RESOLUCION (11) QUE PERMITE LA PRODUCCION DE UN SENSOR ELECTROQUIMICO CAPAZ DE DETERMINAR LA CONCENTRACION DE ANALITO DE FORMA PRECISA EN UNA MUESTRA DE TAMAÑO MUY PEQUEÑO. UN MATERIAL CONDUCTOR ELECTRICO (3) SE FIJA A UN PRIMER SUBSTRATO AISLANTE (4). UN SEGUNDO SUBSTRATO AISLANTE (5) SE FIJA DESPUES AL MATERIAL CONDUCTOR ELECTRICO (3) Y SE ESTRUCTURA MEDIANTE FOTOLITOGRAFIA PARA DEFINIR UN AREA DE ELECTRODO (8). ALTERNATIVAMENTE, EL MATERIAL CONDUCTOR ELECTRICO (3) PUEDE SER DIRECTAMENTE IMPRESO EN UN SUBSTRATO DE TABLERO DE CIRCUITOS IMPRESOS, ESTANDAR (4) EN EL CASO DE UNA ELECTRODO CONTADOR O DE REFERENCIA. EN CUALQUIER CASO, EL SUBSTRATO PUEDE SER RIGIDO O FLEXIBLE. CUANDO LOS ELECTRODOS PRODUCIDOS DE ACUERDO CON LA PRESENTE INVENCION SON USADOS EN UN SENSOR ELECTROQUIMICO QUE INCLUYE UN REACTIVO, LAS AREAS DE ELECTRODO PEQUEÑAS Y ALTAMENTE DEFINIDAS (8,9) PERMITEN REALIZAR MEDIDAS DE ANALITO ELECTROQUIMICO ALTAMENTE PRECISAS EN MUESTRAS DE TAMAÑO MUY PEQUEÑO.
