1. A method of immobilizing a biomolecule for sensing a target species on a substrate to fabricate a nanosensor device for sensing the target species, said method comprising:

  • providing a plurality of carbon nanotubes and a quantity of a biomolecule configured to interact with the target species in an aqueous solution;

    dispersing the plurality of nanotubes and at least some of the quantity of the biomolecule to thereby create a stable suspension of nanotubes and biomolecules in the aqueous solution;

    providing a substrate surface having an electrode surface thereon; and

    simultaneously depositing nanotubes and biomolecules from the stable suspension to at least the electrode surface to thereby immobilize the biomolecules on the substrate.
