A single drop of blood is teeming with microorganisms - imagine if we could see them, and even nanometer-sized viruses, with the naked eye. That's a real possibility with what scientists call a 'perfect lens'. The lens hasn't been created yet but it is a theoretical perfected optical lens made out of metamaterials, which are engineered to change the way the materials interact with light.

Researchers have developed a new technique called SINGLE that provides the first atomic-scale images of colloidal nanoparticles. SINGLE, which stands for 3D Structure Identification of Nanoparticles by Graphene Liquid Cell Electron Microscopy, has been used to separately reconstruct the 3D structures of two individual platinum nanoparticles in solution.

Part of a 1929 prediction by physicist Hermann Weyl - of a kind of massless particle that features a singular point in its energy spectrum called the 'Weyl point' - has finally been confirmed by direct observation for the first time, says an international team of physicists.

Researchers are developing the next generation of gold microstructures, replacing the free-floating particle with pyramid-shaped gold structures anchored to a flat surface. These microstructures are more stable than traditional nanoparticles and focus laser energy into intense electromagnetic near fields.

Scientists have created a new type of room-temperature tunnel device structure in which the tunnel barrier and transport channel are made of the same material, graphene. Such functionalized homoepitaxial structures provide an elegant approach for realization of graphene-based spintronic, or spin electronic, devices.

The Sun can be a better chemist, thanks to zinc oxide nanorod arrays grown on a graphene substrate and 'decorated' with dots of cadmium sulphide. In the presence of solar radiation, this combination of zero and one-dimensional semiconductor structures with two-dimensional graphene is a great catalyst for many chemical reactions.
