Abstract
Se describe un dispositivo de filtracion que incorpora nanoparticulas (1) que son capaces de destruir bacterias, hongos, virus o toxinas. Las nanoparticulas (1) se combinan con un filtro (2). Las nanoparticulas (1) pueden ser perlas que estan adyacentes al filtro (2), un polvo (12) de nanoparticulas (1) que recubra al menos un lado del filtro (2) o impregnado en el filtro (2). Opcionalmente, dos o mas filtros (2) estan contenidos dentro de un alojamiento (3) que tiene una entrada (4) y una salida (5). De preferencia, al menos un filtro (2) tiene una carga electrica igual a la carga electrica de al menos una particula objetivo. Tambien preferentemente, el recubrimiento se lleva a cabo haciendo que el filtro (2) que se va a recubrir tenga una carga electrica opuesta a la carga electrica de las nanoparticulas (1) en el polvo (12). Opcionalmente, el filtro (2) puede ser ya sea hidrofobo o hidrofilo.
