Abstract	We present the preparation, micro-patterning, and electrical property characterization of 3-dimensional PolyFerroCNT™ electrodes (minimum feature size of 200 ± 10 μm, with a height of approximately 200 μm) comprised of polydimethylsiloxane (PDMS), ferrofluid, and graphetized multi-walled carbon nanotubes (G-CNT) for the purpose of creating thermally stable, flexible, conductive, semi-transparent, and biocompatible electrodes with magnetically inducible “active” microstructures. We performed electrical characterizations for different weight percentage of G-CNTs, PDMS, and ferrofluid and demonstrated resistivity as low as 1 KΩ-cm. The electrical property of our nanocomposite electrodes was shown to be a function of not only the weight percentage of its constituents; but also the cure temperature and cure time during the baking step. Further, we have demonstrated successful attachment of oligonucleotides to PolyFerroCNT™ electrodes opening a possibility of using such electrodes in molecular diagnostics and related areas.
