In the green synthesis approaches of silver nanoparticles, do plant extracts solely influence secondary metabolite compounds that act as reducing agents and antioxidants? Or do the antibacterial, antifungal, and other biological activities of the plant extract also impact the formation of silver nanoparticles?
Different plant extracts vary in their phytochemicals that are responsible for the bio-reduction, and subsequently they could alter the nanoparticle synthesis and properties. They may enhance the antibacterial or antifungal potentials of nanoparticles by providing conjugation with multiple microbial cell surface receptors. So, to figure out the difference, you may need to perform FTIR and GC-mass analysis for each extract and the Ag NPs.
Thank you very much for the explanation sir Gehad Al-Arabi .
Allow me to confirm once again: in the context of green synthesis of silver nanoparticles using plant extracts themselves, is it accurate to say that plant extracts not only serve as bioreductors but also retain their secondary metabolite compounds, which can still provide biological activity when AgNPs are formed?
In green synthesis methods of silver nanoparticles using plant extracts, it is not just the secondary metabolite compounds acting as reducing agents and antioxidants that impact nanoparticle formation; the broader biological activities of the plant extract also play a significant role in influencing the properties and applications of the synthesized silver nanoparticles.
