Abstract

A new concept for analyte detection based on the combination of interdigitated capacitor technology with supramolecular structures (see this month's cover picture) is presented. Analyte molecules disturb the hydrogen bonds between pyridone units, and it is this structure-breaking effect (see figure) which is the basis of the sensor detection
