Using Life's Building Blocks to Control Nanoparticle Assembly
Using DNA, the molecule that carries life's genetic instructions, researchers at the U.S. Department of Energy's Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters. view more (2007-08-23)
Targeted nanospheres find, penetrate, then fuel burning of melanoma
Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reported in the Feb. 1 issue of Clinical Cancer Research. view more (2009-02-02)
Nanoparticle Assembly Enters the Fast Lane
The speed of nanoparticle assembly can be accelerated with the assistance of the molecule that carries life's genetic instructions, DNA, a team of researchers at the U.S. Department of Energy's Brookhaven National Laboratory recently found. view more (2006-10-12)
Gold nanoparticles could improve antisense cancer drugs
In the fight against cancer, antisense drugs, which prevent genes from producing harmful proteins such as those that cause cancer, have the promise to be more effective than conventional drugs, but the pace of development of these new drugs has been slow. view more (2006-05-19)
One nano-step closer to weighing a single atom
By studying gold nanoparticles with highly uniform sizes and shapes, scientists now understand how they lose energy, a key step towards producing nanoscale detectors for weighing any single atom. view more (2009-07-28)
Toward a nanomedicine for brain cancer
