Nanoparticles filled with chemotherapeutic drugs can kill drug-resistant breast cancer cells, according to a study published in the scientific journal Biomaterials. Nanoparticles are just as small, or even smaller, than many blood proteins. They can therefore pass through the walls of healthy and sick cells, which make them interesting carriers of drugs against cancer and other diseases. In the present study, researchers from Karolinska Institutet have shown that nanoparticles made from...

An international team of researchers has used pioneering electron microscopy techniques to discover an important mechanism behind the reaction of metallic nanoparticles with the environment. Crucially, the research led by the University of York and reported in Nature Materials, shows that oxidation of metals - the process that describes, for example, how iron reacts with oxygen, in the presence of water, to form rust - proceeds much more rapidly in nanoparticles than at the macroscopic...

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...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
