Characterization of Silver Nanoparticles Fabricated by Green Synthesis Using Urtica Dioica and Lavandula Angustifolia and Investigation of Antimicrobial and Antioxidant

Abstract

Silver nanoparticles (AgNPs) was synthesized from Urtica dioica (UDANP) and Lavandula angustifolia (LAANP) plants. Silver nanoparticles obtained from green synthesis were characterized by UV-Vis, FTIR, SEM, TEM. The DPPH scavenging activities of UDANP were found as 73.58, 84.61, 100, 100, and 100% at 12.5, 25, 50, 100, and 200 mg/L, respectively. On the other hand, DPPH radical scavenging abilities of LAANP were determined as 62.56, 73.07, 78.71, 86.92, and 100% at 12.5, 25, 50, 100, and 200 mg/L, respectively. The ferrous chelating activities of LAANP were found as 7.96, 17.59, 29.45, 41.63, and 59.44% at 12.5, 25, 50, 100, and 200 mg/L, respectively. Besides UDANP was showed 73.58 and 84.61% metal chelating activity at 12.5 and 25 mg/L, respectively. The antimicrobial activity of UDANP and LAANP was performed using broth-dilution method. After the cell viability test of UDANP and LAANP, E. coli cell growth inhibited as 100%.
