DNA lends scientists a hand, revealing new chemical reactions

...now, shifting their focus a bit, they're using the technique to reveal as-yet undiscovered chemical reactions. DNA's inherent sequence selectivity - binding only to other strands with a complementary sequence - means that DNA-templated synthesis can be used to evaluate hundreds of potential chemical reactions ...

Rice finds 'on-off switch' for buckyball toxicity

... industry," Colvin said. "Moreover, we believe the technique can prove useful in tuning the toxicity of other nanoparticles." The researchers postulate that cell death in the tests occurred via physical disruption of the cell membrane by oxygen radical species generated by the buckyballs. Colvin and her collea...
