Building on their creation of the first-ever mechanical device that can measure the mass of individual molecules, one at a time, a team of scientists has created nanodevices that can also reveal their shape. Such information is crucial when trying to identify large protein molecules or complex assemblies of protein molecules.
They may deal in gold, atomic staples and electron volts rather than cement, support beams and kilowatt-hours, but chemists have drafted new nanoscale blueprints for low-energy structures capable of housing pharmaceuticals and oxygen atoms.
The study investigates the ability of amino-functionalized multi-walled carbon nanotubes to cross the Blood-Brain Barrier (BBB) by two ways: in vitro using a co-culture BBB model comprising primary porcine brain endothelial cells and primary rat astrocytes and, in vivo, following a systemic administration of radiolabelled f-MWNTs.
Ash trees in 22 eastern states of U.S.A. are being decimated by emerald ash borers (EABs), an Asian beetle that arrived in Michigan more than two decades ago. The pest has even spread westwards into Kansas and Colorado. Nothing seemed to be effective against EABs, until decoys designed to mimic female EABs were found in 2012 by a group of researchers to be successful in enticing male EABs for mating. Last year, the same researchers found the decoys could be used to electrocute and kill the seduced males.
In an effort that reaches back to the 19th-century laboratories of Europe, a discovery by chemistry researchers establishes new research possibilities for silicon chemistry and the semiconductor industry. The study gives details on the first time chemists have been able to trap molecular species of silicon oxides.
Using a technique that introduces tiny wrinkles into sheets of graphene, researchers have developed new textured surfaces for culturing cells in the lab that better mimic the complex surroundings in which cells grow in the body.
