The green method is not only harmonious to our environment but saves time and is comparatively cheaper than other methods. The current study is aimed to synthesize the silver nanoparticles (AgNPs) using the green method by using the leaves of Loranthus pulverulentus Wall (LPW) which functioned as a reducing as well as capping agent. The synthesis of biogenic AgNPs was confirmed by UV–Vis spectroscopy (UV–Vis.), Scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), and Fourier transform infrared (FTIR). The absorbance maxima of the synthesized AgNPs were observed in the range of 405–435 nm. The SEM was used to find out the size and shape of the synthesized AgNPs, which revealed that the NPs were rectangular having sizes from 05 to 16 nm. XRD revealed that the synthesized NPs were crystalline and face-centered cubic (FCC). EDX analysis reflected the elemental composition of the synthesized product and showed that the percentage of silver = 92. FTIR was used to confirm the functional groups responsible for the reduction and stabilization of silver ions. It revealed that biomolecules present in plant extract were responsible for the reduction and stabilization of silver ions. The effect of temperature, pH, reaction time, silver nitrate concentration, and plant extract concentration on the synthesis of AgNPs were also investigated. The synthesized silver nanoparticles were tested against four bacterial strains which showed strong antibacterial activity. We conclude that biogenic silver nanoparticles could be used as antibacterial agents to treat various diseases.

Loranthus pulverulentus 共轭银纳米粒子的合成及抗菌潜力

绿色方法不仅与我们的环境和谐相处，而且比其他方法节省时间并且相对便宜。目前的研究旨在通过绿色方法利用Loranthus pulverulentus Wall的叶子合成银纳米粒子（AgNPs）。(LPW) 作为还原剂和封端剂。通过紫外-可见光谱 (UV-Vis.)、扫描电子显微镜 (SEM)、X 射线衍射 (XRD)、能量色散 X 射线 (EDX) 和傅里叶变换红外 (FTIR) 证实了生物源 AgNPs 的合成. 在 405-435 nm 范围内观察到合成的 AgNPs 的最大吸光度。SEM 用于确定合成的 AgNPs 的尺寸和形状，结果表明 NPs 为矩形，尺寸为 05 至 16 nm。XRD 显示合成的 NPs 是晶体和面心立方 (FCC)。EDX 分析反映了合成产物的元素组成，显示银的百分比 = 92。FTIR 用于确认负责银离子还原和稳定的官能团。它揭示了植物提取物中存在的生物分子负责银离子的还原和稳定。还研究了温度、pH、反应时间、硝酸银浓度和植物提取物浓度对AgNPs合成的影响。合成的银纳米粒子针对四种表现出强抗菌活性的细菌菌株进行了测试。我们得出结论，生物银纳米颗粒可用作治疗各种疾病的抗菌剂。合成的银纳米粒子针对四种表现出强抗菌活性的细菌菌株进行了测试。我们得出结论，生物银纳米颗粒可用作治疗各种疾病的抗菌剂。合成的银纳米粒子针对四种表现出强抗菌活性的细菌菌株进行了测试。我们得出结论，生物银纳米颗粒可用作治疗各种疾病的抗菌剂。
