Wie Nanopartikel interne Struktur von Flüssigkeiten umordnen

Fast unbemerkt sind sie Teil unseres täglichen Lebens geworden: Nanopartikel führen in Kosmetika, Nahrungsmitteln und Medikamenten, aber auch in Katalysatoren zu besonderen Eigenschaften der Produkte. In den meisten Anwendungsgebieten werden die Nanopartikel in Flüssigkeiten aufgelöst, denn viele ihrer Eigenschaften entstehen an den Grenzflächen. Bisher...

Nanotechnology for clean drinking water

One way of removing harmful nitrate from drinking water is to catalyse its conversion to nitrogen. This process suffers from the drawback that it often produces ammonia. By using palladium nanoparticles as a catalyst, and by carefully controlling their size, this drawback can be partially eliminated. It was research conducted by Yingnan Zhao of the...

New triggered-release nanoparticle mechanism could improve drug delivery

More efficient medical treatments could be developed thanks to a new method for triggering the rearrangement of chemical particles. The new method, developed at the University of Warwick, uses two ‘parent’ nanoparticles that are designed to interact only when in proximity to each other and trigger the release of drug molecules contained within both....
