Abstract
Embodiments of nanoelectronic sensors are described, including sensors for detecting analytes inorganic gases, organic vapors, biomolecules, viruses and the like. A number of embodiments of capacitive sensors having alternative architectures are described. Particular examples include integrated cell membranes and membrane-like structures in nanoelectronic sensors.
