Abstract

leaf extract was successfully utilized as a reducing agent to synthesize silver nanoparticles (AgNPs) in the laboratory. The phytochemicals in the extract helped keep the silver nanoparticles stable and slowed them down. Different methods, such as UV-visible, FT-IR spectroscopies, XRD, and SEM analyses, were used to characterize the size, shape, and morphology of the nanoparticles, and the results showed that the synthesized nanoparticles were spherical and monodispersed. FTIR spectrum streaching vibrations shown stabillization of silver nanoparticles by green extract. On the other hand, these nanoparticles were labelled as (AB) extract silver nanoparticles (AB-AgNPs). The biological synthesis process was proven to enhance the efficacy of the synthesized silver nanoparticles. The effectiveness of AB-AgNPs in fighting cancer could be enhanced specifically for lung cancer (A549 cell line) and breast cancer (MCF7 cell line) by optimizing the necessary conditions. The IC value for A549 cells was 49.52 g mL, while that for MCF7 cells was 78.40 g mL. The effect of AgNPs on both cell lines was assessed using an MTT assay, which showed a dose-dependent cytotoxicity effect. The biosynthesized AB-AgNPs hold great potential as anticancer agents. Their synthesis using leaf extract as a reducing agent was proven to be successful, resulting in spherical and monodispersed nanoparticles that exhibit effective cytotoxicity against cancer cells.

摘要

在实验室中,叶提取物成功地用作还原剂来合成银纳米颗粒(AgNPs)。提取物中的植物化学物质有助于保持银纳米颗粒的稳定性并减缓其聚集。使用了不同的方法,如紫外可见光谱、傅里叶变换红外光谱、X射线衍射和扫描电子显微镜分析,来表征纳米颗粒的尺寸、形状和形态,结果表明合成的纳米颗粒呈球形且单分散分布。傅里叶变换红外光谱的伸缩振动显示绿色提取物对银纳米颗粒起到了稳定作用。另一方面,这些纳米颗粒被标记为(AB)提取物银纳米颗粒(AB-AgNPs)。生物合成过程被证明提高了合成银纳米颗粒的功效。通过优化必要条件,AB-AgNPs对肺癌(A549细胞系)和乳腺癌(MCF7细胞系)的抗癌效果可以得到增强。A549细胞的半数抑制浓度值为(49.52)微克/毫升,而MCF7细胞的半数抑制浓度值为(78.40)微克/毫升。使用MTT法评估了AgNPs对两种细胞系的影响,结果显示出剂量依赖性细胞毒性作用。生物合成的AB-AgNPs作为抗癌剂具有巨大潜力。事实证明,以叶提取物作为还原剂来合成它们是成功的,得到了呈球形且单分散分布的纳米颗粒,这些纳米颗粒对癌细胞表现出有效的细胞毒性。
