Popis: | Recently, green synthesis of silver nanoparticles has attracted much curiosity in the field of life science research. In the present study, we have reported a green method for synthesis of silver nanoparticles (AgNPs) using aqueous seed extract of Phoenix sylvestris L. The green synthesized nanoparticles were characterized by aids of dynamic light scattering, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and Fourier transform-infrared. Further, the study demonstrate the comparative phytochemical analysis as well as antioxidant and antibacterial activity of the extract and Phoenix sylvestris seed generated nanoparticles against acne-causing pathogens, that is, by using a DPPH-scavenging assay and broth microdilution method as well as Kirby–Bauer Disk diffusion method (recommended by CLSI), respectively. Moreover, a concentration-dependent time-kill kinetic studies were also carried out to determine their antimicrobial activity. The seed extract was found a better antioxidant and AgNPs exhibited highly biocidal agent against both the test pathogens, when compared to aqueous extracts. The results obtained indicate that seed extract of P. sylvestris is suitable for synthesizing stable silver nanoparticles, which act as excellent antimicrobial agents with promising treatments for cosmetics embarrassment. |
