Berkeley Lab researchers take cues from nature in designing a programmable nanomaterial for biosensing Taking inspiration from the human immune system, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have created a new material that can be programmed to identify an endless variety of molecules. The new material resembles tiny sheets of Velcro, each just one-hundred nanometers across. But instead of securing your sneakers, this molecular...

Using Gold Nanoparticles To Convert Carbon Dioxide To Carbon Monoxide
2013-10-25 09:25:35

Brown University It’s a 21st-century alchemist’s dream: turning Earth’s superabundance of carbon dioxide — a greenhouse gas — into fuel or useful industrial chemicals. Researchers from Brown have shown that finely tuned gold nanoparticles can do the job. The key is maximizing the particles’ long edges, which are the active sites for the reaction. By tuning gold nanoparticles to just the right size, researchers from Brown University have developed a catalyst that selectively...

Nanoparticles Mixed To Make Multifunctional Materials
2013-10-21 06:34:23

DOE/Brookhaven National Laboratory Standardized technique opens remarkable opportunities for 'mix and match' materials fabrication Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a general approach for combining different types of nanoparticles to produce large-scale composite materials. The technique, described in a paper published online by Nature Nanotechnology on October 20, 2013, opens many opportunities for mixing and matching particles...

Common catalyst cerium oxide opens door to nanochemistry for medicine Scientists at Rice University are enhancing the natural antioxidant properties of an element found in a car’s catalytic converter to make it useful for medical applications. Rice chemist Vicki Colvin led a team that created small, uniform spheres of cerium oxide and gave them a thin coating of fatty oleic acid to make them biocompatible. The researchers say their discovery has the potential to help treat traumatic...

Mammalian Cells Prefer Nanodiscs Over Nanorods
2013-10-07 16:21:24

Georgia Institute of Technology For years scientists have been working to fundamentally understand how nanoparticles move throughout the human body. One big unanswered question is how the shape of nanoparticles affects their entry into cells. Now researchers have discovered that under typical culture conditions, mammalian cells prefer disc-shaped nanoparticles over those shaped like rods. Understanding how the shape of nanoparticles affects their transport into cells could be a major...

Plastic Waste A Hazard For Subalpine Lakes
2013-10-07 13:42:37

Cell Press Many subalpine lakes may look beautiful and even pristine, but new evidence suggests they may also be contaminated with potentially hazardous plastics. Researchers say those tiny microplastics are likely finding their way into the food web through a wide range of freshwater invertebrates too. The findings, based on studies of Italy's Lake Garda and reported on October 7th in Current Biology, a Cell Press publication, suggest that the problem of plastic pollution isn't limited...

Simulations help North and South Dakota researchers decide which technology would make a better solar collector, quantum dot or nanowire A trio of researchers at North Dakota State University, Fargo, and the University of South Dakota have turned to computer modeling to help decide which of two competing materials should get its day in the sun as the nanoscale energy-harvesting technology of future solar panels -- quantum dots or nanowires. Andrei Kryjevski and his colleagues, Dimitri...

Plasmas attack bacterial cells on several levels RUB researchers analyse the mechanism of action of UV photons and radicals As they destroy bacteria very efficiently, plasmas constitute an alternative to chemical disinfectants and potentially to antibiotics, as well. How they achieve this effect has been investigated by biologists, plasma physicists and chemists at the Ruhr-Universität (RUB). Cold atmospheric-pressure plasmas attack the prokaryote’s cell envelope, proteins and DNA....
