DNA Fragments Throw Light on Nuclease Activity
Nuclease activity can be detected by a simple, sensitive, and selective test based on light scattering of carbon nanotubes, with no need for a label.
Nontoxic Nanoparticles
US scientists show the mechanism of toxicity of gold nanoparticles in living cells, and demonstrate that the nanoparticles are not toxic under diagnostic conditions.
Gold Nanoparticles to Beat the Flu
Functionalized gold nanoparticles are used to prevent flu viruses from attaching to and entering cells, in research by German scientists.
