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.

Researchers at the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder (CU) have designed a carbon nanotube knife that, in theory, would work like a tight-wire cheese slicer. In a paper presented this month at the 2006 International Mechanical Engineering Congress and Exposition, the research team announced a prototype nanoknife that could, in the future, become a tabletop tool of biology, allowing scientists to cut and study cells more precisely than they can today.

Researchers at the University of California, Riverside have shown for the first time that carbon nanotubes in a vacuum show excellent conductivity and can be very effective infrared detectors because of their high sensitivity to light.

In less than 20 minutes, researchers at New Jersey Institute of Technology (NJIT) can now seed, heat and grow carbon nanotubes in 10-foot-long, hollow thin steel tubing.

“The work took us three years to develop and get right, but now we can essentially anchor nanotubes to a tubular wall. No one has ever done anything like this before,” said lead researcher Somenath Mitra, PhD, professor and acting chair of NJIT’s Department of Chemistry and Environmental Science. Graduate and post-doctoral students who worked on the project are Mahesh Karwa, Chutarat Saridara and Roman Brukh.

Organic light emitting diodes (OLED) are the technology used in making light emitting fabrics used in cell phones and televisions. The fabrication of flexible OLEDs has up to now been held back by the fragility of the brittle indium tin oxide layer that serves as the transparent electrode. But researchers at the Regroupement Québecois sur les Matériaux de Pointe (RQMP) have found a solution based on carbon nanotubes which they published in the May online issue of Applied Physics Letters.
