Nanopores could provide a new way to sequence DNA quickly, but the physics involved isn't well understood. That's partly because of the complexities involved in studying the random, squiggly form DNA takes in solution. Researchers have simplified matters by using a stiff, rod-like virus instead of DNA to experiment with nanopores. Their research has uncovered previously unknown dynamics in polymer-nanopore interactions.

Physicists have created a silicon nanocavity that allows light to be trapped longer than in other similarly-sized optical cavities. An innovative design approach, which mimics evolutionary biology, allowed them to achieve a 10-fold improvement on the performance of previous nanocavities.

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 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.

Brightly-colored, iridescent films, made from the same wood pulp that is used to make paper, could potentially substitute traditional toxic pigments in the textile and security industries. The films use the same principle as can be seen in some of the most vivid colors in nature, resulting in colors which do not fade, even after a century.
