Ovarian cancer is deadliest of fifth leading cause of death in women worldwide. This is due to advanced-stage disease rate associated with the development of chemoresistance. Hence, the current study emphasizes the process of synthesis of silver nanoparticles (AgNPs) from green chemistry method. Ficus krishnae is a perennial plant, native to India, used in folklore medicine to treat various diseases.
For the development of reliable, ecofriendly, less expensive process for the synthesis of AgNPs against bacterial and ovarian cancer.
The synthesis of silver nanoparticles from stem bark of Ficus krishnae was carried out. The synthesized nanoparticles are subjected by UV-Vis spectrophotometer, scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis and FTIR analysis. The antibacterial efficacy also determined by disc diffusion method, MIC, CFU and growth curve. In vitro cytotoxicity effect of aqueous extract and AgFK nanoparticle in ovarian cancer cell line by MTT assay was performed.
The formation of AgNPs was confirmed by UV-VIS spectroscopic absorbance shown that peak at 435 nm. XRD photograph has indicated the face-centered cubic structure of the synthesized AgNPs. SEM study demonstrated that the size from 160 to 260 nm with interparticle distance, whereas shape is spherical. The particle size were ranging from 15 to 28 nm determined by XRD pattern. The antibacterial and cytotoxicity activity of this nanoparticle has showed a potential activity when compared with standards.
The present study confirms that the biosynthesized AgNPs from Ficus krishnae stem bark extract have a great affiance as antibacterial and anticancer agent.
卵巢癌是全球女性第五大死因中最致命的一种。这是由于晚期疾病发生率与化疗耐药性的发展相关。因此,本研究着重于采用绿色化学方法合成银纳米颗粒(AgNPs)的过程。克里希纳榕是一种多年生植物,原产于印度,在民间医学中用于治疗各种疾病。
开发一种可靠、环保且成本较低的合成抗细菌和卵巢癌AgNPs的方法。
采用克里希纳榕茎皮合成银纳米颗粒。对合成的纳米颗粒进行紫外可见分光光度计、扫描电子显微镜(SEM)、X射线衍射(XRD)分析和傅里叶变换红外光谱(FTIR)分析。还通过纸片扩散法、最低抑菌浓度(MIC)、菌落形成单位(CFU)和生长曲线测定抗菌效果。通过MTT法检测水提取物和AgFK纳米颗粒对卵巢癌细胞系的体外细胞毒性作用。
紫外可见光谱吸光度证实了AgNPs的形成,显示在435nm处有峰值。XRD照片表明合成的AgNPs具有面心立方结构。SEM研究表明,其尺寸在160至260nm之间,颗粒间距离不等,形状为球形。通过XRD图谱测定的粒径范围为15至28nm。与标准品相比,该纳米颗粒的抗菌和细胞毒性活性显示出潜在活性。
本研究证实,从克里希纳榕茎皮提取物生物合成的AgNPs作为抗菌和抗癌剂具有很大的应用前景。
