Abstract

LAS PARTICULAS SUPERPARAMAGNETICAS SE SEPARAN DE UNA SUSPENSION DE LAS MISMAS EN UN PRIMER FLUIDO Y SE VUELVEN A SUSPENDER EN EL MISMO FLUIDO O EN OTRO DISTINTO QUE SE ENCUENTRA EN UN CONTENEDOR, A BASE DE SOMETERLAS A UN PRIMER CAMPO ELECTROMAGNETICO PARA LLEVAR LAS PARTICULAS A UNA SUPERFICIE O ZONA DEL CONTENEDOR Y DESPUES VOLVER A SUSPENDER LAS PARTICULAS EN EL FLUIDO QUE SE ENCUENTRA EN EL CONTENEDOR MEDIANTE UNA SEGUNDA APLICACION DE UN CAMPO MAGNETICO. SE PRESENTA UN APARATO QUE CONTIENE EL CONTENEDOR (1), MEDIOS (2, 3) PARA PRODUCIR DICHAS PRIMERA Y SEGUNDA APLICACIONES DE CAMPOS ELECTROMAGNETICOS, RECEPTACULOS REACTIVOS (7) Y UNA FRASCO DE LAVADO (8). SE PUEDE INCLUIR TAMBIEN UN DISPOSITIVOS CONTADOR DE PARTICULAS Y TAL APARATO SE PUEDE UTILIZAR PARA CONTAR CELULAS.
