Quercetin dietary supplement for the synthesis and stabilization of AgNPs in a neutral aqueous medium and their enhanced long-term antimicrobial activity Letter uri icon

abstract

  • In a dietary supplement presentation, quercetin was used at pH 7 as an efficient reducing and stabilizing agent to obtain silver nanoparticles (AgNPs). They were characterized by UV/Vis, TEM, XRD, and Z-potential to confirm formation and long-term stability. The antibacterial activity was tested against S. aureus and E. coli, high inhibition was found, and their effect remained after 180 days. It is possible to synthesize AgNPs with long-term stability, maintaining size, structure, and enhanced antimicrobial activity under neutral conditions, which has not been reported in the literature. The stability success is attributed to the ingredient present in this supplement.
