Dark, dark nanotechnology

An ideal black object absorbs all of the colors of light and reflects none of them. Researchers at Rice University have demonstrated a new concept based on a low-density nanotube array material that can be engineered to dramatically change an objectâ??s index of refraction and nanoscale roughness, hence, its optical reflection.

Bacteria drop dead on killer surfaces

Work surfaces that kill bacteria on contact could soon be a reality in our homes and hospitals, thanks to researchers from the Curie Institute in Paris. The French group has developed a method for making surfaces bactericidal that it says is straightforward and versatile enough to be widely used.

Picking armchairs from zigzags

Nanotechnology researchers have spent the past few years developing a whole range of methods for separating different types of single-walled carbon nanotube (SWNT), from centrifuging them in a density gradient to attaching diazonium salts and then separating them by electrophoresis. But it now looks as though ion exchange chromatography might provide the best solution, not just being able to separate metallic SWNTs from semi-conducting SWNTs but able to separate every type of SWNT according to its specific electrical properties.

T-cell 'nanotubes' may explain how HIV virus conquers human immune system

String-like connections found between T-cells could be important to how HIV spreads between cells in the human immune system, according to new research published online today in Nature Cell Biology. The newly-discovered strands, named 'membrane nanotubes' by scientists, could help to explain how the HIV virus infects human immune cells so quickly and effectively.
