 Green synthesis of nanoparticles, GNPs, involves the use of natural materials such as plants, bacteria, and fungi to produce metal nanoparticles. This process can be used to create more environmentally friendly products, as well as to develop new applications for existing products. GNPs are often found to contain compounds derived from the original source material, such as sugars, secondary metabolites, and proteins. These compounds may contribute to the unique properties of GNPs, such as antimicrobial, antioxidant, or cytotoxic activity. Additionally, GNPs have been shown to be superior to chemically synthesized nanoparticles in terms of stability and bioactivity. Further research is needed to understand how these compounds interact with the nanoparticle structure and how they affect its physical and chemical properties.
