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.
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.
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.
Researchers from the Martin Research Group at the University of Michigan have demonstrated they can precisely release individual drugs and bioactive molecules at desired points in time by using electrical stimulation of nanotubes.
FePt nanoparticles containing a near-equal atomic percentage of iron and platinum are an important class of artificial nanostructured magnetic nanomaterials. They range in size from 2 to 20 nm in diameter and their magnetic properties change drastically with their size.
Researchers at the Korea Institute of Science and Technology (KIST) succeeded in fabricating a fascinating ZnO nanosheet structure.
Researchers at Jilin University in the PR of China explained to Nanowerk how they developed a simple, large-scale and low-cost route to synthesize IFs.
A novel micro-reactor approach for fabricating self-organzed, photosensitive gold-peapodded silica nanowires has been developed by a group of researchers in Taiwan.
