Gold Nanoparticle Molecular Ruler to Measure Smallest of Life�s Phenomena
Scientists from the U.S. Department Energy�s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have developed a ruler made of gold nanoparticles and DNA that can measure the smallest of life�s phenomena, such as precisely where on a DNA strand a protein attaches itself.

Tiny inhaled particles take easy route from nose to brain
In a continuing effort to find out if the tiniest airborne particles pose a health risk, University of Rochester Medical Center scientists showed that when rats breathe in nano-sized materials they follow a rapid and efficient pathway from the nasal cavity to several regions of the brain, according to a study in the August issue of Environmental Health Perspectives.

Nanotechnology can identify disease at early cellular level
Nanotechnology may one day help physicians detect the very earliest stages of serious diseases like cancer, a new study suggests. It would do so by improving the quality of images produced by one of the most common diagnostic tools used in doctors' offices � the ultrasound machine.

'Custom' nanoparticles could improve cancer diagnosis and treatment
Researchers have developed "custom" nanoparticles that show promise of providing a more targeted and effective delivery of anticancer drugs than conventional medications or any of the earlier attempts to fight cancer with nanoparticles. Designed at the molecular level to attack specific types of cancer without affecting healthy cells, the nanoparticles also have the potential to reduce side effects associated with chemotherapy, the researchers say. Their study was described today at the 231st national meeting of the American Chemical Society, the world�s largest scientific society.
