Abstract

UN PROCESO DE ELABORACION DE MICROCAPSULAS QUE CONSISTE DE (I) APORTAR UNA SOLUCION DE UNA PROTEINA EN UN DISOLVENTE ACUOSO Y (II) VAPORIZAR DICHA SOLUCION PARA CONVERTIRLA EN UN GAS DE MODO QUE SE EVAPORE EL DISOLVENTE ACUOSO, FORMANDO ASI MICROCAPSULAS HUECAS, CARACTERIZADAS POR CONTENER LA SOLUCION ACUOSA UN LIQUIDO MAS VOLATIL QUE EL AGUA. LA PROTEINA ES PREFERIBLEMENTE ALBUMINA Y EL LIQUIDO VOLATIL ES PREFERIBLEMENTE ETANOL. LAS MICROCAPSULAS PUEDEN USARSE COMO AGENTES DE CONTRASTE ECOGENICOS DE ULTRASONIDO.
