An international team of researchers has used nanoparticles to deliver a drug into specific compartments of nerve cells, dramatically increasing its ability to treat pain in mice and rats. The drug that the researchers encapsulated into nanoparticles is an FDA-approved drug used to prevent nausea and vomiting that had previously failed clinical trials as a pain medication.
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a scheme for assembling light-absorbing molecules and water-splitting catalysts on a nanoparticle-coated electrode. The result is the production of hydrogen gas fuel via artificial photosynthesis—a lab-based mimic of the natural process aimed at generating clean energy from sunlight.

Chemists at Northwestern University have used visible light and nanoparticles to quickly and simply make molecules that are of the same class as many lead compounds for drug development. The nanoparticles are known as quantum dots – so small they are only a few nanometers across. But the small size is power, providing the material with attractive optical and electronic properties not possible at greater length scales.

Using computer modeling and an imaging technique called liquid-phase electron microscopy, researchers from the University of Illinois at Urbana-Champaign and Northwestern University pinpointed the individual motions of nanoscale particles as they orient themselves into crystal lattices. The work confirms that synthetic nanoparticles—the fundamental building blocks of many synthetic and biological materials—can assemble in ways far more complex than larger particles, the researchers said, and paves the way to more general applications for mineralization, pharmaceuticals, optics and electronics.

How do we know when graphene, the most widely studied 2-D material, is a defect-free and uniform layer of atoms? Scientists at the U.S. Department of Energy's Ames Laboratory have discovered an indicator that reliably demonstrates a sample's high quality. The researchers were investigating samples of graphene using low-energy electron diffraction and realized that a broad band of diffuse diffraction in the background was actually an intrinsic feature of graphene, but that broad band of diffuse diffraction had been ignored for the past 25 years.
