Glowing future for nanotubes
rsc.org October 30th, 2007 A team of scientists from India and Japan have been the first to make a bundle of nanotubes glow, paving the way for their use as chemical sensors or in optoelectronics. The researchers, led by Talappil Pradeep of the Indian Institute of Technology, Madras, bound gold nanoparticles to single walled carbon nanotubes (SWNTs), which can be either metallic or semiconducting depending on how the carbon atoms that make them up are arranged. The nanoparticles increased the number of defects in the metallic nanotubes, making the entire bundle semiconducting and able to fluoresce.1 'The metal-semiconductor transition enables visible fluorescence by removing the nonradiative decay channels from excited states,' Pradeep explained. 'The emission requires direct interaction of nanotubes with nanoparticles. It disappears when molecular spacers are introduced in between the nanoparticles and SWNTs.'

Radio waves fire up nanotubes in tumors, destroying liver cancer
Rice University November 1st, 2007 Preclinical results reported by M. D. Anderson, Rice in the journal Cancer Cancer cells treated with carbon nanotubes can be destroyed by non-invasive radio waves that heat up the nanotubes while sparing untreated tissue, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center and Rice University has shown in preclinical experiments. The research is posted online and slated to appear in the journal Cancer. The researchers show that the technique completely destroyed liver cancer tumors in rabbits.

Delft University of Technology rotates electron spin with electric field
Delft University of Technology November 1st, 2007 Researchers at the Delft University of Technology's Kavli Institute of Nanoscience and the Foundation for Fundamental Research on Matter (FOM) have succeeded in controlling the spin of a single electron merely by using electric fields. This clears the way for a much simpler realization of the building blocks of a (future) super-fast quantum computer. The scientists will publish their work in Science Express on Thursday 1 November.
