Chemotherapeutic coatings enhance tumor-frying nanoparticles
Durham NC (SPX) Jul 14, 2015
In a move akin to adding chemical weapons to a firebomb, researchers at Duke University have devised a method for making a promising nanoscale cancer treatment even more deadly to tumors. The invention allows an extremely thin layer of hydrogels (think contact lenses) to be deposited on the surface of nanoshells - particles about a hundred nanometers wide designed to absorb infrared light and generate heat. When heated, these special hydrogels lose their water content and release any molecules (s ... read more

Polymer mold makes perfect silicon nanostructures Using molds to shape things is as old as humanity. In the Bronze Age, the copper-tin alloy was melted and cast into weapons in ceramic molds. Today, injection and extrusion molding shape hot liquids ... more		Nanoscale light-emitting device has big profile University of Wisconsin-Madison engineers have created a nanoscale device that can emit light as powerfully as an object 10,000 times its size. It's an advance that could have huge implications for ... more		Nanowires highly 'anelastic' Researchers from Brown University and North Carolina State University have found that nanowires made of zinc oxide are highly anelastic, meaning they return to shape slowly after being bent, rather ... more
				Superslippery islands (but then they get stuck) (Nano)islands that slide freely on a sea of copper, but when they become too large (and too dense) they end up getting stuck: that nicely sums up the system investigated in a study just published in ... more		Ultra-thin, all-inorganic molecular nanowires successfully compounded Nanowires are wired-shaped materials with diameters that are tens of nanometers or less. There are many types of nanowires, including semiconducting composite nanowires, metal oxide composite nanowi ... more
