By melding magnetic and luminescent properties with an easily modified surface, a team of investigators at the National Research Council of Canada have created what could prove to be a highly versatile nanoparticle system for imaging and delivering drugs to tumors.
A new environmental chamber constructed by the Materials Science Division at Argonne allows researchers to watch materials as they grow step-by-step while interacting in elevated-temperature, reactive-gas environments.
University of Wisconsin-Madison mechanical engineers have developed a method for fabricating packages of tiny sensors that measure temperature more accurately than bulk thermocouples. Inserted unobtrusively in critical locations, these metal-embedded micro-thin film thermocouples could more effectively monitor conditions and diagnose problems during manufacturing processes such as injection-molding or die-casting.
Researchers from Rensselaer Polytechnic Institute have engineered nanoscale materials that are blood compatible using heparin, an anticoagulant. The heparin biomaterials have potential for use as medical devices and in medical treatments such as kidney dialysis.
Engineers have created carpets made of tiny cylinders called carbon nanotubes to enhance the flow of heat at a critical point where computer chips connect to cooling devices called heat sinks, promising to help keep future chips from overheating.
Using polymer-coated quantum dots targeted to a molecule found on newly growing blood vessels, a team at the Stanford University has shown for the first time that quantum dots can image the blood supply of a tumor.
