Abstract

Un procedimiento para formar microcápsulas que comprenden (i) proveer una solucion de una proteína en un solvente acuoso y (ii) rociar la solucion en un gas de tal manera que el solvente acuosos se evapore, formando así microcápsulas huecas, caracterizado porque la solucion acuosa contiene un líquido de mayor volatibilidad que el agua; la proteína es preferiblemente albumina y el líquido volátil es preferiblemente etanol; las microcápsulas se pueden usar como agentes de contrastes ecogénicos de ultrasonido.
