Two-dimensional semiconductor comes clean

Scientists demonstrated that they could dramatically improve the performance of graphene by encapsulating it in molybdenum disulfide, an insulating material with a similar layered structure.

Weighing and imaging molecules one at a time

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.

Study explores the interaction of carbon nanotubes and the blood-brain barrier

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.

Simpler nanoscale bioreplication of beetle decoys

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.
