Abstract

Ciertas modalidades están dirigidas a composiciones que comprenden y a un método para producir microesferas de alginato que contienen liposomas encapsulando una variedad de sustancias útiles. Las sustancias importantes que se pueden encapsular en liposomas y cargarse a microesferas de alginato incluyen radioterapéuticos (por ejemplo, renio-188), radiomarcadores (por ejemplo, tecnecio-99m), quimioterapéuticos (doxorubicina), partículas magnéticas (por ejemplo, nanopartículas de hierro de 10 micras) y un material radio-opaco (por ejemplo, contraste de yodo).
