In recent years, metallic nanoparticles have attracted considerable interest due to their intriguing physicochemical properties, small size and surface plasmon behaviour. Among all, silver nanoparticles (AgNPs) display the highest level of commercialization and account for 55.4% of the total nanomaterial-based consumer products available in the market (313, out of 565 products). Silver nanoparticles have been utilized in diverse domains including optoelectronics, biosensors, catalysis, surface enhanced Raman scattering (SERS) and, as anti-microbials.
