Nanoparticle-stabilized liposomes

Liposomes, man-made cells used as drug delivery vehicles, would be more useful if only they could be stabilized against fusion with one another. Researchers at the University of Illinois told Nanowerk that they succeeded in doing exactly that - they stabilized phospholipid liposomes with charged nanoparticles, thereby opening up interesting functional perspectives.

Could nanoparticles be designed to become potent antioxidants?

The responses of cells exposed to nanoparticles have been studied with regard to toxicity, but very little attention has been paid to the possibility that some types of particles can protect cells from various forms of lethal stress.

Nanoscale magnetic materials are a key focus in developing biomedical applications

Spanish researchers developed a simple and inexpensive way to produce well-coated iron nanoparticles. The particles thus obtained present a much stronger magnetic response than any composite material produced up to now involving magnetic nanoparticles encapsulated in inorganic matrices, and the rich chemistry and easy functionalization of the silica outer surface make them promising materials for their application as magnetic carriers.
