The invention belongs to the technical field of composite
medicine materials as well as a preparation method and application thereof, more particularly discloses a
nanoparticle for embedding medicinal Adriamycin. The
nanoparticle has a core-shell type structure with an inner core embedded by an outer shell, wherein the inner core is embedded medicinal adriamycin, and the material for the outer shell is
silicon dioxide; and the preparation method of the
nanoparticle comprises the following steps of: evenly mixing
cyclohexane, a surfactant and n-hexylalcohol, adding a
sodium fluoride solution into the
mixed solution after being evenly mixed to form a reverse-phase
microemulsion; adding adriamycin and tetraethoxysilane into the reverse-phase
microemulsion, and reacting to obtain a nanoparticle
microemulsion system for embedding the adriamycin; adding a silylanization
reagent containing functional groups into the microemulsion
system, stirring for reacting, adding
ethanol and demulsifying, centrifuging and then preparing the nanoparticle for embedding the medicinal adriamycin and modifying the functional groups. The nanoparticle embedding for the adriamycin has good stability, good
biocompatibility, long slow-
release time, large
drug-
loading rate, high
medicine packaging rate, and the like, and has application prospect in the fields of
tumor imaging and treatment.
