Silver nanoparticles synthesized from hydroalcoholic extract

Más información sobre el libro

The study focuses on the innovative synthesis and evaluation of silver nanoparticles (AgNPs) derived from the hydroalcoholic extract of Passiflora edulis Sims seeds. Using cold maceration and HPLC-MS for chemical profiling, the research identified Genisteins as the primary constituent. AgNPs were synthesized through Ag+ reduction and characterized via UV-Vis spectrophotometry and DLS. The antioxidant activity was assessed using the ABTS method, revealing a notable CI50 of 9.23 mg L-1 at pH 4, highlighting the effectiveness of these nanoparticles and the influence of pH on their properties.
