Switchable nanovalves: pH-sensitive pseudorotaxane as reversible gate for drug nanotransporter

We encounter valves every day, whether in the water faucet, the carburetor in our car, or our bicycle tire tube. Valves are also present in the world of nanotechnology. A team of researchers at the University of California, Los Angeles, has now developed a new nanovalve. In contrast to prior versions, which only function in organic solvents, this valve operates in an aqueous environment and under physiological conditions.

In your face - how to win the 'aging conflict'

In our Slow News Friday entry from a few weeks ago we brought you the 'Chantecaille Nano Gold Energizing Cream' at $420 for 1.7 ounces. Fortunately we found a much more affordable alternative at only $149.95 for 1.5 ounces (1 ounce = 28.35 grams). So rather than $8.70 per gram you can get nanotechnology face cream for only $3.20 per gram.

American Society for Laser Medicine and Surgery's scientific conference shines the light on cutting-edge laser research

The ASLMS conference is traditionally regarded as the premier forum for the introduction of the newest breakthroughs in laser diagnostics and technology. Therefore, some of the research and techniques presented are only in the early stages of development. In addition to nearly 2,000 laser specialists in aesthetic surgery, dermatology, ophthalmology, oncology, urology, gynecology and dentistry, about 160 industry exhibitors will be on hand to showcase their latest products.

Nanoparticles affect pollutant toxicity

Other organic (carbon-based) chemicals are known to have an effect on the toxicity of pollutants to plant and animal life. But nanoparticles like C60 have unique and altered properties compared to larger particles, and so they may have a very different effect on the toxicity and availability of pollutant molecules. The nanoparticles themselves may also be inherently toxic.

Researchers engineer new polymers to change their stiffness and strength when exposed to liquids

An interdisciplinary team of researchers from the departments of macromolecular science and engineering and biomedical engineering at the Case School of Engineering and the Louis Stokes Cleveland Department of Veterans Affairs Medical Center has published ground-breaking work on a new type of polymer that displays chemoresponsive mechanic adaptability - meaning the polymer can change from hard to soft plastic and vice versa in seconds when exposed to liquid.

Nanoscale tool allows scientists to study membrane proteins one at a time

Researchers at Rockefeller University have now created a tiny tool, more than 10,000 times smaller than the diameter of a human hair, capable of encasing single membrane proteins from living cells. The new system, which resembles a nanoscale sushi roll, will allow investigators to individually stimulate these key proteins with specific molecules and signals in order to precisely define the biological reactions that result.

Tuberculosis bacterium is double-protected

The first 3-D images that disclosure a double membrane surrounding mycobacteria were recorded by Martinsried scientists, ending a long scientific debate about the mycobacterial outer membrane and opening new pathways to improve the development of chemotherapeutic substances against tuberculosis.
