As such, green synthesis is regarded as an important tool to reduce the destructive effects associated with the traditional methods of synthesis for nanoparticles commonly utilized in laboratory and industry. They are environmentally friendly because the toxic chemicals produced during the biosynthesis of the nanoparticles can be degraded with the help of enzymes present in the microbes. In this work, we summarized the fundamental processes and mechanisms of green synthesis approaches, especially for bimetallic of Cu and Ag nanoparticles using natural extracts. The synthesized Cu-Ag nanoparticles were characterized by XRD, FT-IR, PSA, FL, and TGA. The antibacterial activity was tested on B. subtilis, E. coli, Staphylococcus, Enterobacter and Pseudomonas. The stability of nanoparticles and the associated surface engineering techniques for achieving biocompatibility are also discussed. Finally, we covered applications of such synthesized products to environmental remediation in terms of antimicrobial activity.
