We describe a new architecture for spin-tronic magnetic devices, using a biologically modified, metal coated, peptide nanotube process which results in tubular, magnetic nanowires.@footnote 1,2@ The magnetic nano-wires are formed from a polypeptide backbone, coated with nickel, or iron, or with multilayers. The morphology of the tubes is that of a hollow, cylindrical metal pipe, with widths from 20-500nm, and lengths of up to a few microns. By functionalizing the ends of the tubes with special molecules, the nano-tubes can be "wired" to specific attachment sites on a substrate by molecular recognition. We call this a "smart-wire" concept, since the instructions for "wiring" the circuits are built into the molecular nanostructures themselves. In this paper, we describe magnetic and electronic transport measurements on aligned Nickel nanotube arrays and individual nanotubes, using both conventional and scanned-probe techniques. @FootnoteText@ @footnote 1@ Matsui, H.; Gologan, B., J.
