This study presents a novel approach to fabricate silver nanoparticles (AgNPs) using the poisonous plant, leaf extract. The formation of AgNPs was confirmed by a color change from green to dark brown and validated by UV analysis. FTIR analysis identified functional groups on the AgNPs, while Zeta potential analysis assessed their stability. TEM analysis established an average diameter of 18 nm and a spherical morphology for the nanoparticles. LC MS analysis coupled with database searches revealed the presence of diverse bioactive compounds, including flavonoids, nucleotides, dipeptides, enzymes, and glycosides. These compounds are postulated to act as reducing agents in the leaf extract-mediated synthesis process. Moreover, the bio-fabricated AgNPs exhibited noteworthy anticancer properties against DLA cells. In addition, AgNPs displayed substantial antimitotic effects in an assay involving root cells. These findings underscore the potential of the AgNPs as cytotoxic agents. The biosynthesized AgNPs showed antimicrobial activity against various bacterial pathogens, including , , and . Furthermore, the AgNPs exhibited outstanding radical-scavenging properties in the DPPH assay, suggesting their potential application in antioxidant therapies. The study collectively highlights the successful synthesis of AgNPs through a green, biocompatible approach, and demonstrates their promising potential for anticancer, antimitotic, and radical-scavenging applications.
本研究提出了一种利用有毒植物叶提取物制备银纳米颗粒(AgNPs)的新方法。AgNPs的形成通过颜色从绿色变为深棕色得以证实,并通过紫外分析进行了验证。傅里叶变换红外光谱(FTIR)分析确定了AgNPs上的官能团,而zeta电位分析评估了它们的稳定性。透射电子显微镜(TEM)分析确定了纳米颗粒的平均直径为18 nm且呈球形形态。液相色谱-质谱(LC MS)分析结合数据库搜索揭示了多种生物活性化合物的存在,包括黄酮类化合物、核苷酸、二肽、酶和糖苷。据推测,这些化合物在叶提取物介导的合成过程中充当还原剂。此外,生物合成的AgNPs对DLA细胞表现出显著的抗癌特性。此外,在涉及根细胞的实验中,AgNPs显示出显著的抗有丝分裂作用。这些发现强调了AgNPs作为细胞毒性剂的潜力。生物合成的AgNPs对包括[具体细菌名称1]、[具体细菌名称2]和[具体细菌名称3]在内的多种细菌病原体具有抗菌活性。此外,AgNPs在二苯基苦味酰基自由基(DPPH)测定中表现出出色的自由基清除特性,表明它们在抗氧化疗法中的潜在应用。该研究共同突出了通过绿色、生物相容性方法成功合成AgNPs,并展示了它们在抗癌、抗有丝分裂和自由基清除应用方面的广阔前景。
