Dragged into shape: Suspensions of rod-shaped tobacco mosaic virus self-assemble under shear. When combined with dewetting on a hydrophobic surface, contiguous and parallel arrays of virus fibers are deposited over macroscopic length scales (see schematic). The virus-protein-coat functionality can be used for the directed bioconjugation of metallic particles to make anisotropically conductive virus wires.
