MAGNETIC COMPOSITE, PREPARATION METHOD AND USE THEREOF

摘要

A magnetic composite, preparation method and use thereof are provided. The magnetic composite is multilayer core-shell architecture with Fe3O4 nanoparticle cores and an A-b-poly(ethylene glycol)-b-poly(glycerol mono(meth)acrylate) triblock copolymer shell, in which "A" is poly(basic amino acid) segment and its derivative. The magnetic composite has low toxicity, can penetrate the cell membrane and can be used for the drug delivery carriers.
