Aptamer Attached to An Electrode Coated with Carbon Nanotubes (image) Wiley Share Print E-Mail Caption This graphic shows an aptamer attached to an electrode coated with single-walled carbon nanotubes interacts selectively with bacteria. The resulting electrochemical response is highly accurate and reproducible and starts at ultra-low bacteria concentrations, providing a simple, selective method for pathogen detection.
