Abstract

Ag particles with the nano dimensions possess exceptional physical as well as chemical properties that mainly depends on the synthetic route. The traditional methods for synthesizing nanostructures are expensive, hazardous, and environmentally unfriendly. To address these challenges, various economical, biocompatible routes have been adopted for Ag nanostructures using natural origin like fungi, plants, bacteria and so on. This review compiles the various natural sources, which are being examined in the fabricating Ag nanostructures, which may be plants, bacteria, fungi, and biopolymers. The mechanism for the growth of Ag nanostructures have also been explored. Finally, the review asses the optical sensing application of Ag nanostructures.
