1. A biosensing device comprising:

  • a substrate;

    at least one electrically conductive lead on the substrate;

    an insulating layer covering the lead, the insulating layer having an aperture exposing a portion of the lead;

    a nanostructured microelectrode adapted by means of an electrocatalytic reporter system to generate a charge in response to a biomolecular stimulus, wherein the nanostructured microelectrode is fractal;

    at least one probe molecule attached to said microelectrode; and

    wherein said microelectrode is in electrical communication with the exposed portion of the lead.
