Silver nanoparticles (AgNPs) have emerged as promising multifunctional agents in biomedical applications due to their notable antimicrobial and anticancer properties. In this study, we present a green, sustainable, and cost-effective method for synthesizing AgNPs using the bulb extract of Anemone coronaria, an underutilized plant part that allows year-round resource-efficient production. The synthesized AgNPs were characterized by UV-Visible spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR). The nanoparticles exhibited a characteristic UV-Vis absorption peak at 425 nm, spherical morphology with an average size of 29 nm, and a face-centered cubic crystalline structure. FTIR analysis confirmed the presence of phytochemicals involved in the reduction and stabilization of AgNPs. The biosynthesized AgNPs showed potent antibacterial activity against both Gram-positive and Gram-negative bacteria, and demonstrated significant cytotoxic effects on cancer cells while sparing normal cells. Apoptosis induction, cell cycle arrest, and gene expression analyses further validated their anticancer efficacy. These findings highlight the therapeutic potential and biocompatibility of Anemone coronaria-derived AgNPs, offering a green nanotechnological approach for future biomedical applications.
由于其显著的抗菌和抗癌特性,银纳米颗粒(AgNPs)已成为生物医学应用中颇具前景的多功能试剂。在本研究中,我们提出了一种绿色、可持续且经济高效的方法,利用冠状银莲花的鳞茎提取物合成AgNPs,冠状银莲花是一种未被充分利用的植物部分,可实现全年资源高效生产。通过紫外可见光谱、扫描电子显微镜(SEM)、能量色散X射线光谱(EDS)、X射线衍射(XRD)和傅里叶变换红外光谱(FTIR)对合成的AgNPs进行了表征。纳米颗粒在425nm处呈现出特征性的紫外可见吸收峰,呈球形形态,平均尺寸为29nm,具有面心立方晶体结构。FTIR分析证实了参与AgNPs还原和稳定的植物化学物质的存在。生物合成的AgNPs对革兰氏阳性菌和革兰氏阴性菌均表现出强大的抗菌活性,并对癌细胞显示出显著的细胞毒性作用,同时对正常细胞无损害。凋亡诱导、细胞周期阻滞和基因表达分析进一步验证了其抗癌功效。这些发现突出了冠状银莲花衍生的AgNPs的治疗潜力和生物相容性,为未来的生物医学应用提供了一种绿色纳米技术方法。
