Iron Oxide Silica Core Shell Nanoparticles

Iron Oxide Silica Core Shell Nanoparticles: Core-shell nanoparticles are highly functional materials with modified properties. Sometimes properties arising from either core or shell materials can be quite different. The properties can be modified by changing either the constituting materials or the core to shell ratio. Because of the shell material coating, the properties of the core particle such as reactivity decrease or thermal stability can be modified, so that the overall particle stability and dispersibility of the core particle increases. Ultimately, particles show distinctive properties of the different materials employed together. The purpose of the coating on the core particle are many fold, such as surface modification, the ability to increase the functionality, stability, and dispersibility, controlled release of the core, reduction in consumption of precious materials, and so on.
