Bug detectors : Multiple arrays of aptamer‐functionalized single‐walled carbon‐nanotube field‐effect transistors (SWNT‐FETs) can be combined with the most probable number method as a simple, fast screening platform for the detection of microorganisms. The picture indicates the binding events of Escherichia coli on such SWNT‐FET arrays, which showed a conductance decrease of more than 50% after binding.
