Strands of DNA have been used as tiny scaffolds to create superconducting nanodevices that demonstrate a new type of quantum interference phenomenon. These nanowire quantum interference devices (NQIDs), which comprise a pair of suspended superconducting wires as thin as three to four molecular diameters (5 nm to 15 nm), could be used to measure magnetic fields and to map out the phase of the order parameter in regions of superconductivity.
