Feasibility of quercetin dietary supplement as reducing and stabilizing agent: Green route of silver nanoparticles using a bioactive flavonoid

This work focused on investigating whether quercetin from a dietary supplement can be used as an efficient reducing and stabilizing agent to obtain suitable silver nanoparticles (AgNPs) through a green synthesis. Antibacterial activity was tested against S. aureus, E. coli, and P. mirabilis for finding high inhibition values using this new route, even more significant than the values reported in current literature. Results stated that it is possible to synthesize spherical AgNPs with excellent stability and antimicrobial activity using a dietary supplement (low purity 20%). The success of this filing is due to the significant solubility provided by the other ingredients present in the dietary supplement.
