Nano-Leuchtkugeln auf Wanderschaft

Nanopartikel spielen eine wesentliche Rolle bei der Entwicklung zukuenftiger diagnostischer und therapeutischer Methoden fuer Tumorerkrankungen, beispielsweise als Transporter fuer Wirkstoffe oder als Kontrastmittel. Aufnahme und Verteilung von Nanopartikeln im Tumorgewebe haengen dabei stark von der Partikelgroesse ab. Um dies systematisch untersuchen zu koennen, haben Wissenschaftler jetzt einen Satz fluoreszierender Nanopartikel verschiedener Durchmesser zwischen 10 und 150 nm hergestellt.

Physicists observe exotic state in an unconventional superconductor

A new fractional vortex state observed in an unconventional superconductor may offer the first glimpse of an exotic state of matter predicted theoretically for more than 30 years. University of Illinois physicists, led by Raffi Budakian, describe their observations of a new fractional vortex state in strontium ruthenium oxide (SRO).

Self-assembling structures open door to new class of materials

Researchers at the University of Illinois and Northwestern University have demonstrated bio-inspired structures that self-assemble from simple building blocks: spheres. The helical 'supermolecules' are made of tiny colloid balls instead of atoms or molecules. Similar methods could be used to make new materials with the functionality of complex colloidal molecules.

Polymer with amazing self-healing properties

Materials with self-healing properties could help extend the durability of products and make repairs easier. Krzysztof Matyjaszewski and his co-workers at Carnegie Mellon University (Pittsburgh, USA) and Kyushu University (Japan) have now developed a polymer that can repair itself when irradiated with UV light - over and over again.

Tissue engineering meets nanotechnology: A look at tomorrow's medicine

Tissue engineers seek to develop functioning substitutes for damaged tissues and organs. Generally, this means seeding cells onto 3-dimensional porous scaffolds made of biomaterials, which provide mechanical support and instructive cues for the developing engineered tissue. Now it's time to go to the next level, and make complex tissues that can really do things - contract, release growth factors, conduct electrical signals and more. Things our own cells and tissues do.
