Representation of the role of active molecules in green metallic nanoparticle synthesis. (A) Microorganism obtained from raw sample is cultured on a plate. (B) Culture is harvested and purified before it is inoculated in sterile nutrient broth with metal ion solution. Methods are taken to promote homeostasis for subsequent nanoparticle synthesis. (C) Metal ions are reduced to metal nanoparticles, facilitated by microorganism’s active molecules. The proposed active molecule mechanism reflected in this figure is the intracellular conversion of metal ion to metal nanoparticle through an enzymatic reduction oxidation process. (D) Nanoparticles are collected and analyzed for purity and formation. Stability and reducing properties from microorganism can be observed in final product.
