Rice physicists kill cancer with 'nanobubbles'.February 4,2010.
Using lasers and nanoparticles, scientists at Rice University have discovered a new technique for singling out individual diseased cells and destroying them with tiny explosions. The scientists used lasers to make "nanobubbles" by zapping gold nanoparticles inside cells. In tests on cancer cells, they found they could tune the lasers to create either small, bright bubbles that were visible but harmless or large bubbles that burst the cells.Source:Rice University

A new testing method is being developed to detect cancer soon after the tumor has formed. It will identify acteristic substances in the blood which accompany a certain type of tumor. The first steps in the development have already been completed.Source:Fraunhofer-Gesellschaft
Magnetic nanoparticles show promise for combating human cancer.February 1,2010.
Scientists at Georgia Tech and the Ovarian Cancer Institute have further developed a potential new treatment against cancer that uses magnetic nanoparticles to attach to cancer cells, removing them from the body. The treatment, tested in mice in 2008, has now been tested using samples from human cancer patients. The results appear online in the journal Nanomedicine.Source:Georgia Institute of Technology

Dry printing of nanotube patterns to any surface could revolutionize microelectronics.January 22,2010.
Watch a gecko walk up a wall. It defies gravity as it sticks to the surface no matter how smooth it appears to be. What's happening isn't magic. The gecko stays put because of the electrical attraction – the van der Waals force – between millions of microscopic hairs on its feet and the surface.The principle applies to new research at Rice University reported this week in the online version of the journal ACS Nano. But in this case, the hairs figuratively come off the gecko and plant themselves on the wall.Source:Rice University

High, not flat: nanowires for a new chip architecture.February 2,2010.
Nowadays, a myriad of silicon transistors are responsible to pass on the information on a microchip. The transistors are arranged in a planar array, i.e. lying flat next to each other, and have shrunk down already to a size of only about 50 nanometers. Further miniaturization of transistors with a planar structure will soon come to an end due to fundamental physical limits. Still, even smaller transistors are desirable in order to continuously improve their functions while reducing the cost of the electronics.Source:Forschungszentrum Dresden Rossendorf
