Silver nanoparticles in solution

Silver nanoparticles are widely used as a broad-based antimicrobial when incorporated into bandages, paints, keyboard and clothing. Like gold, silver has a strong plasmon resonance that can be tuned by adjusting the particle shape (e.g. spheres, cubes and plates). When carefully dried, silver nanoparticles can be re-suspended without aggregation. Silver can also be used to coat gold nanoparticles to produce bi-metallic core/shell nanoparticles.

Other silver particles

Silver nanoplates are surface plasmon resonant (SPR) platelet-shaped nanoparticles that have extremely large absorbing and scattering cross-sections across the visible and near-IR regions of the spectrum. By precisely controlling the plate diameter and thickness, the nanoplate’s optical resonance can be tuned to peak at specific wavelengths (550–1300 nm).
