In this study, silver nanoparticles (AgNPs) were in situ generated on the surface of cellulose matrix using leaf extract of cissampelos pareira (LCP) by environmentally benign green synthesis. The morphological and structural properties of synthesized cellulose silver nanocomposites (Cel/LCP/Ag-NCs) were characterized by different spectral studies such as UV–visible spectroscopy, SEM, TEM, FT-IR, AFM, DRS, PL, Lifetime, XPS and XRD. Silver nanoparticles were obtained in the cellulose matrix with an average size of 34.26 nm and with antioxidant activity which has been evaluated by ABTS (70.34% at 100 µg/mL) and DPPH (81.65% at 100 µg/mL) methods. The antimicrobial properties of cellulose, Cel/LCP, Cel/LCP (10 mM, 30 mM and 50 mM AgNO₃), tested on 13 microorganisms were determined using disk diffusion method. The most effective nanocomposites (Cel/LCP/10, 30 and 50 mM AgNO₃), Cel/LCP/50 mM AgNO₃ afforded the best antimicrobial properties because increasing the concentration of AgNO₃ solution, the zone of inhibition also increased. The prepared cellulose silver nanocomposites synthesized by leaf extract of cissampelos pareira shows the potential to be applied in the future development of therapeutics and biomedical applications.

在这项研究中，银纳米粒子 (AgNPs ) 通过环境良性绿色合成，使用cissampelos pareira (LCP) 的叶提取物在纤维素基质表面原位生成。合成的纤维素银纳米复合材料（Cel/LCP/Ag-NCs）的形态和结构特性通过不同的光谱研究进行表征，如紫外-可见光谱、SEM、TEM、FT-IR、AFM、DRS、PL、Lifetime、XPS和XRD。银纳米颗粒在纤维素基质中获得，平均尺寸为 34.26 nm，具有抗氧化活性，经 ABTS（100 µg/mL 时为 70.34%）和 DPPH（100 µg/mL 时为 81.65%）方法评估。纤维素、Cel/LCP、Cel/LCP（10 mM、30 mM 和 50 mM AgNO ₃)，使用圆盘扩散法测定了 13 种微生物。最有效的纳米复合材料（Cel/LCP/10、30 和 50 mM AgNO ₃）Cel/LCP/50 mM AgNO ₃提供了最好的抗菌性能，因为增加 AgNO ₃溶液的浓度，抑菌圈也增加了。由cissampelos pareira的叶提取物合成的纤维素银纳米复合材料显示出在未来治疗学和生物医学应用发展中的应用潜力。
