Chemists develop new method for observing chemical reactions of individual silver nanoparticles   Chemists at Ruhr-Universität Bochum have developed a new method of observing the chemical reactions of individual silver nanoparticles, which only measure a thousandth of the thickness of a human hair, in real time.

Cocktail of nanoparticles and contaminants may have harmful effects on human cells   Researchers warn that a combination of nanoparticles and contaminants may form a cocktail that is harmful to our cells. In their study, 72 pct. of cells died after exposure to a cocktail of nano-silver and cadmium ions.         Researchers modify nanoparticles to improve their uptake in gastrointestinal tract   Nanoparticles show great promise as diagnostic tools and drug delivery agents. The tiny particles, which scientists can modify with drugs, dyes or targeting molecules, can travel in the circulation and squeeze through small spaces into cells and tissues.

Researchers design nanotubes that can align water molecules into a square rod   First, according to Rice University engineers, get a nanotube hole. Then insert water. If the nanotube is just the right width, the water molecules will align into a square rod.       Measuring nanocrystal length and thickness in just 40 minutes analysis time   Postnova Analytics reports on how Asymmetrical Flow Field Flow Fractionation coupled to Multi Angle Light Scattering (AF4-MALS) has been successfully used to characterize a polydisperse cellulose nanocrystal for size and thickness in just 40 minutes analysis time.       Nanoparticle Generation System from Dolomite   The Polymer Nanoparticle Generation System provides a solution for production of monodisperse polymer nanoparticles such as PLGA, PEG, PVC.       Nanoparticle Tracking Analysis   Nanoparticle tracking analysis (NTA) is a method for visualizing and analyzing particles in liquids. NTA suspends small particles (~10-1000 nm) in a liquid, this allows for the determination of a size distribution profile.       Researchers engineer peptide nanoparticles to outsmart biological system and target kidney cells   Remember the scene in the movie Mission: Impossible when Tom Cruise has to sneak into the vault? He had to do all sorts of moves to avoid detection. That's what it's like to sneak a targeted drug into a kidney and keep it from getting eliminated from the body.       Catalytic nanoparticles can effectively prevent tooth decay   Combine a diet high in sugar with poor oral hygiene habits and dental cavities, or caries, will likely result.       New nanoplatform technology may reverse drug-resistance in renal cell carcinoma   A research team led by Arun Iyer, Ph.D., assistant professor of pharmaceutical sciences in the Eugene Applebaum College of Pharmacy and Health Sciences at Wayne State University, has developed a nanoplatform technology that works in combination with existing chemotherapeutic drugs that may reverse drug-resistance in renal cell carcinoma.
