What can Nanochemistry do for Chemical and Biological Sensing?
So what is next for nanochemical and biochemical sensor research? Shouldn’t we be trying to find the next glass pH electrode, rather than trying to squeeze that extra fraction of a percent out of our tried and tested materials?
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.
