(A) Sequence-specific programmed DNA strands using rolling circle amplification (RCA) to generate a template for enzyme attachment. (B) Assembly of Au-NP-functionalized glucose oxidase (GOx) on the RCA-synthesized template, and the biocatalytic enlargement of Nanogold to gold nanowire structures. (C) AFM images of the resulting gold nanostructures: (I) a large 12 μm2 image; (II and III) images of different single wires and the respective cross-section analyses. (D) (I) Scanning electron microscopy image of the biocatalytically generated gold nanowires and (II) the enlargement of one domain of the wire. (III) Energy-dispersive spectrometry analysis of the resulting gold nanowire (from Wilner et al., 2009; used with permission).
