Medical science is placing high hopes on nanoparticles as in future they could be used, for example, as a vehicle for targeted drug delivery. An international team of researchers has for the first time succeeded in assaying the stability of these particles and their distribution within the body. Their results show that a lot of research is still needed in this field.

Plasmonics demonstrates how light can be guided along metal surfaces or within nanometer-thick metal films. It works like this: on an atomic level, metal crystals have a very organized lattice structure. The lattice contains free electrons, not closely associated with the metal atoms, that interact with the light that hits them.

Researchers have developed a material suited for photovoltaics. For the first time, a functioning organic solar cell consisting of a single component has been produced on the basis of metal-organic framework compounds (MOFs). The material is highly elastic and might also be used for the flexible coating of clothes and deformable components.

In a typical experiment involving biological material such as nanoscale hairs, it would usually be sufficient to use an electron microscope to create an image of the surface of the specimen. This research, however, required to look inside the ant hairs and produce a cross-section of the structure's interior. The relatively weak beam of electrons from a standard electron microscope would not be able to penetrate the surface of the sample.
