FIG. 1.

(a) Schematic of a 7 bit planar magnetic microtag showing the polymer substrate (backbone) with the magnetic elements deposited on its surface, the spatial sequence of which determined a digital code. (b) A 5 bit “multicoercivity” tag with the corresponding F-MOKE image.

FIG. 2.

(a) The molecular structure of the chosen fluorophores with its functionalities highlighted. (b) 50× fluorescence microscope image of SU-8 backbones (on substrate) following etching, oxidation, and coupling to the fluorophore.

Image of FIG. 3.
FIG. 3.

Hysteresis loops for an array of elliptical Co elements with minor axis and major axes (a) and (b) —the switching field was applied along the long large axis; (c) scanning electron microscopy image of such a tag; (d) superconducting quantum interference device magnetometry hysteresis loop showing a 2 bit tag with magnetic layers of 25 and 50 nm switching at different applied fields.
