X-ray lenses for nanoanalytics

Progress in the field of nanotechnology can only be achieved, if analytical methods for the characterization of nanostructures continuously improve. Due to the structures' small size visible light cannot be utilized for nanoanalytical techniques. In point of fact, microscopic methods with electron waves or X-rays must be applied here, as the wavelengths, they work with, are small enough. Multilayer Laue lenses (MLL) offer a most promising approach to developing highest resolution X-ray optics.

What mode of action do nanomaterials have in liver and intestine?

What mode of action do nanomaterials ingested via food have in liver and intestine? Which factors determine their toxicity? Due to the large number of different nanomaterials, it is hardly possible to test every one for its toxic properties. For this reason, specific properties for the classification of nanomaterials are to be examined within the scope of the Franco-German research project SolNanoTox, which began on 1 March 2014.

Nano-imaging probes molecular disorder

Using a newly developed imaging method, researchers show that thin-film organic semiconductors contain regions of structural disorder that could inhibit the transport of charge and limit the efficiency of organic electronic devices.

Long-range tunneling of quantum particles

The quantum tunnel effect manifests itself in a multitude of well-known phenomena. Experimental physicists have now directly observed quantum particles transmitting through a whole series of up to five potential barriers under conditions where a single particle could not do the move.

Antibodies from the desert as guides to diseased cells

Researchers have developed nanoparticles that not only bypass the body's defence system, but also find their way to the diseased cells. This procedure uses fragments from a particular type of antibody that only occurs in camels and llamas.
