Mesoporous silica hollow capsules embedded with magnetic nanoparticles

Abstract

Our method for synthesizing the mesoporous silica hollow capsules (MSHCs) was combined with the Layer-by-Layer method to integrate the magnetic nanoparticles (mNPs) onto the core template for the MSHC synthesis. The resultant magnetic MSHCs (mMSHCs) were monodisperse as the conventional MSHCs, and the mNPs were embedded on the inner surface of the mesoporous silica shell. The same mesoporous structure as in the MSHCs was confirmed in the mMSHCs and the properties of the mNPs were maintained even after being incorporated into the mMSHCs.
