Nanoparticle opens the door to clean-energy alternatives
Cheaper clean-energy technologies could be made possible thanks to a new discovery. An important chemical reaction that generates hydrogen from water is effectively triggered -- or catalyzed -- by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth. The research team is led by Raymond Schaak, a professor of chemistry at Penn State University.

Light-carved 'nano-volcanoes' hold promise for drug delivery
Researchers from North Carolina State University have developed a method for creating "nano-volcanoes" by shining various colors of light through a nanoscale "crystal ball" made of a synthetic polymer. These nano-volcanoes can store precise amounts of other materials and hold promise for new drug-delivery technologies.

New quantum dot technique combines best of optical and electron microscopy
Researchers working at NIST have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture to image nanoscale features. Combining the best features of optical and scanning electron microscopy, the fast, versatile, and high-resolution technique allows scientists to view surface and subsurface features potentially as small as 10 nanometers in size.

Luminous bacterial proteins detect chemicals in water
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf have developed a simple color sensor principle which facilitates the detection of residual medications, trace metals from industrial process waters, and many other substances. This is the concept: If the analyzed sample shines red, then the water is 'clean;' if its color turns green, however, then it contains the substances the scientists wish to detect. The researchers recently published their concept in the scientific journal Sensors and Actuators B: Chemical.

Nanotechnology helps track and improve drug action in pancreatic cancer
Scientists from Sydney's Garvan Institute of Medical Research, in collaboration with colleagues from the Beatson Institute for Cancer Research in Glasgow UK, have been able to show ways in which we can markedly improve drug targeting of solid tumors, using tiny 'biosensors' along with new advanced imaging techniques. In real time and in three dimensions, these technologies can show us how cancers spread and how active cancer cells respond to a particular drug.

Hebrew University student wins award for research on safer drugs through skin applications
New, more efficient drug formulations designed to treat illnesses through skin applications -- thus avoiding serious side effects associated with oral drug-taking -- have been developed by a student at the Hebrew University of Jerusalem. The method is based on utilizing skin-permeable proteins that are inserted into nano-structured gels.

Shape of nanoparticles points the way toward more targeted drugs
A new study involving Sanford-Burnham's Erkki Ruoslahti, M.D., Ph.D., contributing to work by Samir Mitragotri, Ph.D., at the University of California, Santa Barbara, found that the shape of nanoparticles can enhance drug targeting. The study found that rod-shaped nanoparticles -- or nanorods -- as opposed to spherical nanoparticles, appear to adhere more effectively to the surface of endothelial cells that line the inside of blood vessels.

The secret life of knots
The scientific journal Macromolecules dedicates the cover of this month's issue (available online from June 11th) to a research coordinated by Cristian Micheletti of the International School for Advanced Studies (SISSA). Micheletti and his colleagues, that include Luca Tubiana (a former SISSA student, now working at the Josef Stefan Institute of Ljubljana) and Angelo Rosa (a researcher at SISSA) simulated the dynamics of the movements with which a polymer tends to knot.

A new study by researchers at UC Santa Barbara provides clues into the understanding of the behavior of the charged molecules or particles in ionic liquids. The new framework may lead to the creation of cleaner, more sustainable, and nontoxic batteries, and other sources of chemical power. The research was published in an early online edition of the Proceedings of the National Academy of Sciences.

Promising material for lithium-ion batteries
Laptops could work longer and electric cars could drive farther if it were possible to further increase the capacity of their lithium-ion batteries. The electrode material has a decisive influence on a battery's capacity. So far, the negative electrode typically consists of graphite, whose layers can store lithium atoms. Scientists at the Technische Universitaet Muenchen have now developed a material made of boron and silicon that could smooth the way to systems with higher capacities.

New microfluidic method expands toolbox for nanoparticle manipulation
Researchers at the University of Illinois have developed a new flow-based method for manipulating and confining single particles in free solution, a process that will help address current challenges faced by nanoscientists and engineers. The "microfluidic trap" is capable of 2-D particle manipulation using the sole action of fluid flow.
