Soft core, hard shell – the latest in nanotechnology

Nanoparticles are the smallest particles capable of reaching virtually all parts of the body. Researchers use various approaches to test ways in which nanoparticles could be used in medicine – for instance, to deliver substances to a specific site in the body such as a tumor. For this purpose, nanoparticles are generally coated with organic materials because their surface quality plays a key role in determining further targets in the body. If they have a water-repellent shell, nanoparticles are quickly identified by the body's immune system and eliminated.
