Indeed, researchers have found that the passage of electrons through a bucky ball in a transistor is correlated to the spinning of the ball around its centre of mass. Moreover, since bucky balls look like molecular ball bearings, it has been thought that they may be useful as lubricants for use in automobile brakes. Now a team of researchers at the University of Bologna (Italy) and the University of Liverpool (UK) have carried out detailed molecular dynamics simulations to understand the motion of bucky...

Wed, 31 Oct 2007 16:42:17 +0100 http://www.nanotechnologyworld.co.uk/index.php?option=com_content&task=view&id=589&Itemid=2 Peter Cummings, John R. Hall Professor of Chemical Engineering at Vanderbilt, will receive the 2007 American Institute of Chemical Engineers (AIChE) Nanoscale Science and Engineering Forum Award at the institute’s annual meeting in November. Wed, 31 Oct 2007 16:27:21 +0100 http://www.nanotechnologyworld.co.uk/index.php?option=com_content&task=view&id=588&Itemid=2 There are two aspects to creating an effective drug: finding a chemical compound that has the desired biological effect and minimal side-effects and then delivering it to the right place in the body for it to do its job. With the support from a $478,000, five-year CAREER award from the National Science Foundation, Eva Harth is tackling the second part of this problem. She is creating a modular, multi-functional drug delivery system that promises simultaneously to enhance the effectiveness and reduce undesirable side-effects of a number of different drugs. Wed, 31 Oct 2007 16:21:54 +0100 http://www.nanotechnologyworld.co.uk/index.php?option=com_content&task=view&id=587&Itemid=2 The National Institute of Biomedical Imaging and Bioengineering (NIBIB), part of the National Institutes of Health (NIH), today announced the award of more than $12 million in grants to support research and development of potentially high-impact, innovative technologies to advance health care.

Wed, 31 Oct 2007 16:13:30 +0100 http://www.nanotechnologyworld.co.uk/index.php?option=com_content&task=view&id=586&Itemid=2 Carbon nanotubes (CNTs) have shown great potential for use as cellular probes. As “nanopipes” they can be used to transport liquids to or from cells and inject solutions or drugs directly into individual cells and individual organelles within the cells. In addition, because of the small diameters of the carbon nanotubes induce little damage to cells upon penetration. By making these probes able to sense within the cells, information about chemical interactions within the cells could be found. Surface-enhanced Raman Spectroscopy (SERS) has this capability.
