The present study was aimed to synthesize the silver nanoparticles from Wang. and evaluating its biomedical applications. The leaves of collected and subjected for the standard procedure of Soxhlet extraction using distilled water as a solvent. With the help of an aqueous extract AgNPs were synthesized from silver nitrate using phyto-reduction method. Further, synthesized AgNPs were characterized using several analytical techniques such as UV, FTIR, SEM-EDX, XRD, particles size and zeta potential. Synthesized AgNPs were tested for antibacterial, antioxidant, anticancer for lung cancer cell line and flowcytometry-based pathway studies. The visual observation confirmed the formation of AgNPs from the aqueous extract by changing yellow to brown colour formation. Further, characterization techniques also confirmed the formation of AgNPs. Antibacterial activity results showed that the tested AgNPs were potent against bacterial pathogens with a higher zone of inhibition. Further, the antioxidant and anticancer activity of AgNPs revealed that the AgNPs have exhibited significant results with a good percentage of inhibition. Further, the flow cytometry studies confirmed that the AgNPs inducing apoptosis and cell cycle arrest in lung cancer. The phytochemicals of plant have successfully synthesized AgNPs. In the case of performed biological activity, the synthesized silver nanoparticles exhibited potent activity. In future these AgNPs can be taken for molecular and in vivo studies to identify their efficacy using in vivo and molecular models.
本研究旨在从王(未明确具体植物)中合成银纳米颗粒并评估其生物医学应用。采集该植物的叶子,以蒸馏水为溶剂,按照索氏提取的标准程序进行提取。借助水提取物,采用植物还原法从硝酸银合成银纳米颗粒。此外,使用紫外可见光谱(UV)、傅里叶变换红外光谱(FTIR)、扫描电子显微镜-能谱仪(SEM-EDX)、X射线衍射(XRD)、粒度分析和zeta电位等多种分析技术对合成的银纳米颗粒进行表征。对合成的银纳米颗粒进行了抗菌、抗氧化、针对肺癌细胞系的抗癌以及基于流式细胞术的通路研究测试。视觉观察通过颜色从黄色变为棕色证实了从水提取物中形成了银纳米颗粒。此外,表征技术也证实了银纳米颗粒的形成。抗菌活性结果表明,测试的银纳米颗粒对细菌病原体具有强效作用,抑菌圈较大。此外,银纳米颗粒的抗氧化和抗癌活性表明,银纳米颗粒表现出显著的结果,抑制率良好。此外,流式细胞术研究证实,银纳米颗粒可诱导肺癌细胞凋亡和细胞周期停滞。该植物的植物化学物质已成功合成银纳米颗粒。在进行的生物活性研究中,合成的银纳米颗粒表现出强效活性。未来,这些银纳米颗粒可用于分子和体内研究,以使用体内和分子模型确定其功效。
