1. An array of nanoscale apertures comprising:

  • a transparent substrate having a cladding layer disposed on its surface, the cladding layer having a plurality of nanoscale apertures extending therethrough;

    each nanoscale aperture having walls and a base, wherein an isolation layer is on the walls and on a portion of the base of the nanoscale aperture;

    wherein a portion of the base of the nanoscale aperture comprises an island of substrate surrounded by isolation layer;

    wherein the size of the opening of each nanoscale aperture, including the isolation layer, is larger than the width of the island of substrate.
