Carbon nanotubes and aptamers: New biosensor detects extremely low bacteria concentrations quickly, easily and reliably

23-Jul-2009 - Bacterial diseases are usually detected by first enriching samples, then separating, identifying, and counting the bacteria. This type of procedure usually takes at least two days after arrival of the sample in the laboratory. Tests that work faster, in the field, and without complex sample ...
