Abstract
Superparamagnetic nanoparticles hold much promise for applications in biomedical fields, such as targeted drug delivery, magnetic resonance imaging, therapeutic agents and bioseparation. The core/shell architectures designed by combining magnetic nanoparticles core with silica shell make it possible for in vivo applications. The core/shell structures with different types will have different application prospects. This review provides a brief overview of recent progress in the synthesis and nanotheranostic applications of magnetic materials/silica core/shell nanoparticles with different configurations.
Keywords: Core/shell, Fe3O4 nanoparticles, hollow structures, mesoporous structures, nanotheranostics, SiO2 coating.
