Bismuth nanowires have intriguing electronic and energy-harvesting application possibilities. However, fabricating these materials with high quality and in large quantities is challenging. Researchers have now demonstrated a new technique to produce single- crystal nanowires atop arbitrary substrates, including glass, silicon, and metal, when an intermediate layer of vanadium is present.

Scientists describe a novel protocol to obtain different types of nanostructures from a single helical polymer and certain metal salts. An outstanding characteristic of these macromolecules is that their helicity can be tuned by the action of diverse external stimuli such as temperature, polarity or metal ions. Consequently, these polymers act as sensors.
