New Antibacterial Material Based on Gold Nanoparticles

Bacteria love to colonize surfaces inside your body, but they have a hard time getting past your rugged, salty skin. Surgeries to implant medical devices often give such bacteria the opportunity needed to gain entry into the body cavity, allowing the implants themselves to act then as an ideal growing surface for biofilms.

Nano-Coated Silver Textiles Lose Less Silver During Washing

If it contains 'nano', it doesn't primarily leak 'nano': at least that's true for silver-coated textiles, explains Bernd Nowack of the Technology and Society division at Empa. During each wash cycle a certain amount of the silver coating is washed out of the textiles and ends up in the waste water. Empa analysed this water; it turned out that nano-coated textiles release hardly any nano-particles.

Cooperation in Heat Shock Protein Observed Using Foerster Resonance Energy Transfer Methodology

As in a successful football match, all actors in a cell must play in perfect coordination. A typical example for this kind of cooperation can be seen in the heat shock protein Hsp90, which controls the proper folding of other proteins. Together with a second molecule, the co-chaperone P23, it splits the energy source ATP to release the energy it needs to do its work.

Addition of Water Molecules Leads to Increase in Distance Between Graphite Oxide Layers

Physicists from Umeå University and Humboldt University in Berlin have solved a mystery that has puzzled scientists for half a century. They show with the help of powerful microscopes that the distance between graphite oxide layers gradually increases when water molecules are added. That is because the surface of graphite oxide is not flat, but varies in thickness with "hills" and "valleys" of nanosize. The new findings are published in the scientific journal Nano Letters.
