    Description
    Silver nanowires are one-dimensional nanostructures with diameters below 100 nm and several micrometers in length, usually available as colloidal suspension dispersed in alcoholic solvents, glycols, or water.  Silver nanowires possess low light absorption in the visible region and have been investigated as a competitive alternative to replace indium tin oxide (ITO) in transparent conductive electrodes. Due to the high surface area and antimicrobial activity of Ag, recently a myriad of applications has also emerged in catalysis and biology fields. NanoScientifica RECY Silver Wires are fabricated from certified 100% ultrapure recycled silver metal. Our utmost target is to expand to 90% of our nanomaterials  portfolio  with massive use of recycled metal sources in the next 2 years.

    Structural features

    The nanowires structure resembles high-aspect-ratio (> 1000) nanoparticles with pentagonal cross-section, which emerges from the symmetry breaking of the face-centered cubic lattice of Ag driven by adsorption of polymeric capping agents to specific facets of nanocrystal.
