Abstract

UN BIODETECTOR (1) Y UN METODO PARA DETERMINAR EL NIVEL DE HEMATOCRITOS EN UNA MUESTRA DE SANGRE PURA (11) UTILIZANDO UNA TECNICA ELECTROQUIMICA. EL BIODETECTOR (1) INCLUYE ELECTRODOS DE TRABAJO (4) Y CONTRAELECTRODOS (5). UNA MEMBRANA POROSA (9) SE IMPREGNA CON UN COMPUESTOS ELECTROACTIVO Y SE DESPLAZA ESPACIALMENTE DE LA SUPERFICIE DE LOS ELECTRODOS (4, 5). CUANDO UNA MUESTRA DE SANGRE PURA (11) SE APLICA AL SUSTRATO POROSO (9), SE FORMA UNA MEZCLA DEL COMPUESTO ELECTROACTIVO Y LA SANGRE (11). LA MEZCLA SE POSA SOBRE LOS ELECTRODOS (4, 5) Y SE APLICA UNA DIFERENCIA POTENCIAL SUFICIENTE COMO PARA OXIDAR O REDUCIR EL COMPUESTO ELECTROACTIVO Y GENERAR UNA CORRIENTE. ESTA CORRIENTE SE MIDE Y CORRELACIONA CON EL NIVEL DE HEMATOCRITOS.
