These rods have a diameter in the range of tens of nanometers, making them the thinnest silver wires in the world. Such wires can be synthesized by electrochemically depositing silver into a nanoporous aluminum oxide template. One of the most interesting applications for this nanomaterial are electrochemical sensors, flexible conductive materials and glues that conduct heat and electricity. In order to see such nanowires, one needs a powerful scanning electron microscope (SEM).
