It is now possible to synthesise bimetallic nanowires made from silver and gold whose length can be precisely controlled thanks to new experiments by researchers in Spain, Germany, Belgium and France. Since the wires made also have roughly the same molecular weight, their “surface plasmon resonances” can be tailored too – in the near- and mid-infrared regions of the electromagnetic spectrum. These nanostructures could be used in a variety of different applications, from metamaterials to solar energy harvesting and biosensing………
