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.

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.
