Scientists at the National Institute of Standards and Technology (NIST) and the University of Maryland, College Park, have built a practical, high-efficiency nanostructured electron source. Described in the journal Nanotechnology*, this new, patent-pending technology could lead to improved microwave communications and radar, and more notably to new and improved X-ray imaging systems for security and health-care applications.

Tiny particles filled with a drug could be a new tool for treating cancer in the future. A new study published by Swedish scientists in Particle & Particle Systems Characterization shows how such nanoparticles can be combined to secure the effective delivery of cancer drugs to tumour cells - and how they can be given properties to make them visible in MR scanners and thus rendered trackable.

Researchers from North Carolina State University have developed a way to melt or “weld” specific portions of polymers by embedding aligned nanoparticles within the materials. Their technique, which melts fibers along a chosen direction within a material, may lead to stronger, more resilient nanofibers and materials.

Making new insights into the nanoworld a reality! An international team working with scientists from the University of Stuttgart and the Max Planck Institute for Solid State Research in Stuttgart have put the conditions in place to examine proteins and other nanostructures with the help of nuclear spin spectroscopy. This is a method that reveals the structure of a material, however, on nanoscopic samples it previously involved enormous technical complexity.

Scientists developed a model of how crystalline particles of a material form depending on their physical properties. Magnetite nanoparticles are used by some bacteria to orient themselves along the Earth’s magnetic field lines. Understanding how they grow could be helpful in generating nanoparticles with the desired properties.
