A new, simple technique to produce ordered arrays of metal nanotubes has been developed by scientists in Moldova. The method works by electroplating in conductive nanotemplates routinely fabricated by anodic etching of semiconductor substrates in salty water. The result could be important for making plasmonic devices, photonic crystals, catalysts for energy conversion and chemical and biological sensors.
