Abstract

UN APARATO PARA LA DETERMINACION CUALITATIVA Y/O CUANTITATIVA DE ANALITOS EN UNA MUESTRA EN PARTICULAR BIOLOGICA MEDIANTE ENLACES RECEPTOR - LIGANDO CON UN DISPOSITIVO DE MAGNETIZACION PARA LA OBTENCION DE UN CAMPO MAGNETICO EN EL LUGAR DE LA MUESTRA A ANALIZAR Y CON UNA INSTALACION DE DETECCION PARA MEDIR LAS PROPIEDADES MAGNETICAS DE LA MUESTRA, SE CARACTERIZA PORQUE EL DISPOSITIVO DE MAGNETIZACION (11 '' ; 11 " ) ES TA COLOCADO DE TAL MANERA EN EL ESPACIO CON RESPECTO AL DISPOSITIVO DE DETECCION (71, 8, 9, 10; 16; 20), QUE EL CAMPO MAGNETICO CREADO POR LA MAGNETIZACION EN EL DISPOSITIVO DE MAGNETIZACION (11 '' ; 11 " ), SE REDUCE EN EL SITIO QUE OCUPA LA MUESTRA A ANALIZAR DURANTE LA MEDIDA Y EN UNA CANTIDAD DE AL MENOS 10 VECES, PREFERIBLEMENTE 1.000 O MAS, O POR EL HECHO DE QUE HAY UN DISPOSITIVO DE CONEXION QUE PUEDE QUITAR EL CAMPO MAGNETICO DEL DISPOSITIVO DE MAGNETIZACION (11; 21) EN EL LUGAR DE LA MUESTRA A ANALIZAR (12) DURANTE UN PERIODO PREFIJADO, PARTICULARMENTE DURANTE LA FASEDE MEDIDA DEL DISPOSITIVO DE DETECCION (71, 8, 9, 10; 16; 20). ESTO PERMITE NUEVOS PROCESOS PARA DETECCION MAGNETORELAXOMETRICA DE ANALITOS O PARA LA DETECCION DE ANALITOS POR MEDIO DE MEDIDA DE REMANENCIA, DE MANERA RUTINARIA Y ECONOMICA, TANTO IN VITRO COMO IN VIVO.
