Nanoparticles could aid biohazard detection, computer industry
...low to begin with; when the salts are dissolved in liquid
at the concentration that Buriak's group needs to form nanoparticles, a test tube full of the solution is worth only pennies. But despite the low market value of the chemical solutions themselves, the effect Buriak's group has discovered may nonethel...

DNA separation by entropic force offers better resolution
...e sieves. Ordinarily, a long chain DNA molecule in liquid
will clump into a roughly spherical shape, and to move through a sieve it must uncoil and slide in lengthwise. The researchers found that this movement involves an entropic force which causes DNA molecules that are only partially within a sieve to wi...
