Fighting cancer with lasers and nanoballoons that pop
Researchers are developing a better delivery method for cancer drugs by encapsulating the drugs in nanoballoons -- which are tiny modified liposomes that, upon being struck by a red laser, pop open and deliver concentrated doses of medicine.

A pocket-size ultrasonic nebulizer employing a novel nozzle improves inhalers
Inhalation is an increasingly important route for non-invasive drug delivery for both systemic and local applications. Control of particle size and output plays a critical role in the efficient and effective delivery of oft en expensive medications to the lung. Drugs designed to treat pulmonary diseases or for systemic absorption through the alveolar capillary bed require optimum particle sizes (1 to 6 μm) for effective delivery.

Structural insights into the inner workings of a viral nanomachine
Researchers at the Virginia Tech Carilion Research Institute are using new nanoscale im-aging approaches to shed light on the dynamic activities of rotaviruses, important pathogens that cause life-threatening diarrhea in young children. Once a rotavirus enters a host cell, it sheds its outermost protein layer, leaving behind a double-layered particle (DLP). These DLPs are the form of the virus that produces messenger RNA molecules, which are critical for launching the infection.

Making the most of carbon nanotube-liquid crystal combos
Dispersions of carbon nanotubes with liquid crystals have attracted much interest because they pave the way for creating new materials with added functionalities. Now, a study published in EPJ E by Marina Yakemseva and colleagues focuses on the influence of temperature and nanotube concentration on the physical properties of such combined materials.

A breakthrough in creating invisibility cloaks, stealth technology
Scientists have managed to create artificial nanostructures that can 'bend light,' called metamaterials. But the challenge has been making enough of the material to turn invisibility cloaks into a practical reality. The work of Debashis Chanda at the University of Central Florida, however, may have just cracked that barrier.

Never say never in the nano-world
'On rare occasions, one may observe events that never happen on the macroscopic scale such as, for example heat transfer from cold to hot which is unheard of in our daily lives,' says Christoph Dellago, professor in computational physics at the University of Vienna and coauthor of the present publication in the renowned journal Nature Nanotechnology.

Fabricating nanostructures with silk could make clean rooms green rooms
Tufts University engineers have demonstrated that it is possible to generate nanostructures from silk in an environmentally friendly process that uses water as a developing agent and standard fabrication techniques. This approach provides a green alternative to the toxic materials commonly used in nanofabrication while delivering fabrication quality comparable to conventional synthetic polymers. Nanofabrication is at the heart of manufacture of semi-conductors and other electronic and photonic devices.

Scientists watch nanoparticles grow
With DESY's X-ray light source PETRA III, Danish scientists observed the growth of nanoparticles live. The study shows how tungsten oxide nanoparticles are forming from solution. These particles are used for example for smart windows, which become opaque at the flick of a switch, and they are also used in particular solar cells. The team around lead author Dr. Dipankar Saha from Århus University present their observations in the scientific journal Angewandte Chemie - International Edition.

Nanotube coating helps shrink mass spectrometers
Nanotechnology is advancing tools that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety. When paper used to collect a sample was coated with carbon nanotubes, the voltage required was 1,000 times reduced, the signal was sharpened and the equipment was able to capture far more delicate molecules. The research is detailed in a designated 'very important paper' by the journal Angewandte Chemie.
