外文摘要：The focal aim of the study was to prepare silver nanoparticles (AgNPs) derived from the leaf extract of Goniothalamus wightii (Gw) and determine the potential bio-applications. The presence of biosynthesized Gw-AgNPs and composition was confirmed by UV visible spectroscopy, and XRD analysis. The FT-IR spectrum was used to confirm the existence of different functional groups that act as capping and reducing agents. Zeta revealed the surface negative charge, and HR-TEM confirmed the spherical form of the Gw-AgNPs. The anti-bacterial activity was tested on four pathogen Pseudomonas aeruginosa, Staphylococcus epidermidis, S. aureus and Escherichia coli, exhibits a strong toxic activity against microorganism and the results recorded that Gw-AgNPs could be a promising antioxidant agent. The Gw-AgNPs against MCF-7 cells is about 50% and holds at 40 μg/mL in 24 h and 60 μg/mL in 48 h. The larvicidal activity of Gw-AgNPs at various concentrations against fourth instar larvae treated, had the highest mortality rate in Aedes aegypti and culex quinquefasciatus (83.33%) 25 mg/L for 48 h and the environmental effects of photocatalytic degradation activities against methylene blue and highest degradation was observed at 98% within 150 min. Overall the results of the study established that the importance of Gw-AgNPs and could be used as potent disruptive bio-material for biomedical and pharma-industrial applications. ? 2022 Taylor & Francis Group, LLC.
