- Preparation method of core-shell structured magnetic nanoparticle

摘要

(a) introducing a functional group into the central nanoparticle to modify the surface thereof; (b) treating the center nanoparticle with a catechol functional group-containing compound to introduce the catechol functional group into the central nanoparticle; (c) forming a layer of the supercritical nanoparticles around the center nanoparticle by introducing the superpowder nanoparticles onto the surface of the central nanoparticle; And (d) forming a silica shell so as to surround the layer of the super-fine magnetic nanoparticles.
