Nanotechnology has been recognized as a highly interdisciplinary field of the twenty-first century, with diverse applications in biotechnology, healthcare, and material science. One of the most commonly employed non-toxic nanoparticles, magnesium oxide nanoparticles (MgO NPs), is simple, inexpensive, biocompatible, and biodegradable. Several researchers are interested in the biosynthesis process of MgO NPs through chemical and physical approaches. This is because of their simplicity, affordability, and environmental safety. In the current study, green MgO-Chitosan-Pluronic F127-Escin (MCsPFE) NPs have been synthesized and characterized via various techniques like UV-visible, Fourier-transform infrared spectroscopy, Energy dispersive X-ray composition analysis, Transmission electron microscopy, field emission scanning electron microscopy, X-ray Diffraction, Photoluminescence, and Dynamic light scattering analyses. The average crystallite size of MCsPFE NPs was 46 nm, and a face-centered cubic crystalline structure was observed. Further, the antimicrobial effectiveness of NPs against diverse pathogens has been assessed. The cytotoxic potential of the nanoparticles against MDA-MB-231 cell lines was evaluated using the MTT test, dual AO/EB, JC-1, DCFH-DA, and DAPI staining procedures. High antimicrobial efficacy of MCsPFE NPs against Gram-positive and Gram-negative bacterial strains as well as was observed. The findings concluded that the NPs augmented the ROS levels in the cells and altered the Δψm, leading to the initiation of the intrinsic apoptotic cell death pathway. Thus, green MCsPFE NPs possess immense potential to be employed as an effective antimicrobial and anticancer treatment option.
纳米技术已被公认为是21世纪一个高度跨学科的领域,在生物技术、医疗保健和材料科学等方面有着广泛的应用。氧化镁纳米颗粒(MgO NPs)是最常用的无毒纳米颗粒之一,它简单、廉价、具有生物相容性且可生物降解。一些研究人员对通过化学和物理方法合成MgO NPs的过程感兴趣。这是因为这些方法简单、经济且环境安全。在当前的研究中,已通过紫外可见光谱、傅里叶变换红外光谱、能量色散X射线成分分析、透射电子显微镜、场发射扫描电子显微镜、X射线衍射、光致发光和动态光散射分析等各种技术合成并表征了绿色MgO-壳聚糖-普朗尼克F127-七叶皂苷(MCsPFE)纳米颗粒。MCsPFE纳米颗粒的平均微晶尺寸为46nm,并观察到面心立方晶体结构。此外,还评估了纳米颗粒对多种病原体的抗菌效果。使用MTT试验、双AO/EB、JC-1、DCFH-DA和DAPI染色程序评估了纳米颗粒对MDA-MB-231细胞系的细胞毒性潜力。观察到MCsPFE纳米颗粒对革兰氏阳性和革兰氏阴性细菌菌株具有高抗菌效力。研究结果表明,纳米颗粒增加了细胞内的活性氧水平并改变了线粒体膜电位,从而启动了内源性凋亡细胞死亡途径。因此,绿色MCsPFE纳米颗粒具有作为有效的抗菌和抗癌治疗选择的巨大潜力。
