Pure carbon nanotubes pass first in vivo test. ‘In the first experiments of their kind, researchers at Rice University and The University of Texas M. D. Anderson Cancer Center have determined that carbon nanotubes injected directly into the bloodstream of research lab animals cause no immediate adverse health effects and circulate for more than one hour before they are removed by the liver.
The findings are from the first in vivo animal study of chemically unmodified carbon nanotubes, a revolutionary nanomaterial that many researchers hope will prove useful in diagnosing and treating disease. The research will appear in this week’s online edition of the Proceedings of the National Academy of Sciences.’ [Read the whole article]
Bio-inspired assembly of nanoparticle building blocks. ‘Chemists at Rice University have discovered how to assemble gold and silver nanoparticle building blocks into larger structures based on a novel method that harkens back to one of nature’s oldest known chemical innovations – the self-assembly of lipid membranes that surround every living cell.
The research appears in the Nov. 29 issue of the Journal of the American Chemical Society (JACS 2006, 128, 15098).
Researchers believe the new method will allow them to create a wide variety of useful materials, including extra-potent cancer drugs and more efficient catalysts for the chemical industry. The method makes use of the hydrophobic effect, a biochemical phenomena that all living creatures use to create membranes, ultra-thin barriers of fatty acids that form a strong, yet dynamic, sack around the cell, sealing it from the outside world.’ [Read the whole article]
