Abstract

"DISPOSITIVO DE FILTRAçãO QUE INCORPORA NANOPARTìCULAS". Trata-se de um dispositivo de filtração que incorpora nanopartículas (1) que são conhecidas como dotadas de capacidade de destruir bactérias, fungos, vírus ou toxinas. As nanopartículas (1) são combinadas com um filtro (2) . As nanopartículas (1) podem ser pelotas adjacentes ao filtro (2), um pó (12) de nanopartículas (1) que reveste pelo menos um lado de um filtro (2), ou impregnado em um filtro (2). Opcionalmente, dois ou mais filtros (2) são contidos dentro de um invólucro (3) que tem uma entrada (4) e uma saída (5). De preferência, pelo menos um filtro (2) tem uma carga elétrica que é idêntica à carga elétrica de pelo menos uma partícula alvo. Também de preferência, o revestimento é obtido quando um filtro (2) a ser revestido contém uma carga elétrica que é oposta a uma carga elétrica contida pelas nanopartículas (1) no pó (12) . Opcionalmente, um filtro (2) pode ser hidrofóbico ou hidrofílico.
