1. An electronic system for selectively detecting and identifying a plurality of chemical or biological species, comprising:

  • an array of nanostructure sensing devices containing;

    a first nanostructure sensing device comprising a first nanostructure, at least two contact electrodes electrically connected by the first nanostructure and a protective coating on the contact electrodes, the first nanostructure sensing device having a selectivity for sensing a first species;

    a second nanostructure sensing device comprising a second nanostructure, at least two contact electrodes electrically connected by the second nanostructure and a protective coating on the contact electrodes, the second nanostructure sensing device having a selectivity for sensing a second species; and

    a processing system to deconvolute and analyze signals from the array to provide identification of chemical or biological species.
