Abstract
ESTA INVENCION PROPORCIONA UN NUEVO PROCESO PARA PRODUCIR PARTICULAS DE POLIMERO FLUORESCENTE SENSIBLE MAGNETICAMENTE QUE CONTIENEN PARTICULAS DE NUCLEO POLIMERICO REVESTIDAS UNIFORMEMENTE CON UNA CAPA DE POLIMERO QUE CONTIENE OXIDO DE METAL SENSIBLE MAGNETICAMENTE. UNA AMPLIA VARIEDAD DE PARTICULAS POLIMERICAS CON TAMAÑOS QUE OSCILAN ENTRE 1 Y 100 MICRAS PUEDEN UTILIZARSE COMO PARTICULAS NUCLEO Y TRANSFORMARSE EN PARTICULAS DE POLIMERO SENSIBLES MAGNETICAMENTE. LA SUPERFICIE DE ESTAS PARTICULAS DE POLIMERO SENSIBLE MAGNETICAMENTE PUEDEN REVESTIRSE ADEMAS CON OTRA CAPA DE POLIMERO FUNCIONALIZADO. ESTAS PARTICULAS DE POLIMERO FLUORESCENTE SENSIBLE MAGNETICAMENTE PUEDEN UTILIZARSE PARA EL ACOPLAMIENTO PASIVO O COVALENTE DE MATERIAL BIOLOGICO COMO ANTIGENOS, ANTICUERPOS, ENZIMAS O HIBRIDACION DE ADN/ARN Y SON USADOS COMO FASE SOLIDA PARA VARIOS TIPOS DE PRUEBAS INMUNOLOGICAS, ENSAYOS DE MUESTRAS DE HIBRIDACION ADN/ARN, PURIFICACION DE AFINIDAD, SEPARACION DE CELULA, Y OTRAS APLICACIONES MEDICAS, DIAGNOSTICAS E INDUSTRIALES.
