The perpetual lack of advanced strategies to prevent aggressive breast cancer with multiple categories represents challenging scientific society problems. Reduced graphene oxide- can treat disease, which was recently investigated due to its ability to induce apoptosis-based death. This research tested the chemotherapeutics in vitro efficacy of reduced graphene oxide embedded with gold and silver nanoparticles toward drug-sensitive breast cancer cells (MCF-7) and their cytotoxicity. Synthesis of the Au-Ag/rGO-5FU nanocomposites has been conducted using a wet chemical approach with chitosan aid as a pore directing and capping agent. The particle structure and morphology well characterized using different systems. HR-TEM shows a narrow-sized distribution of less than 100 nm, which is proper for cell membranes and medical use. The physical combination of the nanocomposite and 5-FU drug has been conducted mechanically using wet chemistry. The Au/Ag/rGO-5FU material's high activity enables it to produce reactive oxygen radicals, which display a potential against MCF-7 cell lines. All the results, including those obtained via cytometry, use the combination of Au/Ag/rGO-5FU to show a more substantial anticancer influence and more drug stability than pure 5-FU.
长期缺乏针对多种类型侵袭性乳腺癌的先进预防策略是科学界面临的具有挑战性的问题。还原氧化石墨烯能够治疗疾病,最近因其诱导凋亡性死亡的能力而受到研究。本研究测试了负载金和银纳米颗粒的还原氧化石墨烯对药物敏感型乳腺癌细胞(MCF-7)的体外化疗效果及其细胞毒性。采用湿化学方法,以壳聚糖作为孔导向和封端剂,合成了Au-Ag/rGO-5FU纳米复合材料。使用不同系统对颗粒结构和形态进行了充分表征。高分辨率透射电子显微镜显示粒径分布狭窄,小于100纳米,适合细胞膜和医学应用。纳米复合材料与5-氟尿嘧啶药物的物理结合是通过湿化学方法机械实现的。Au/Ag/rGO-5FU材料的高活性使其能够产生活性氧自由基,对MCF-7细胞系显示出潜力。所有结果,包括通过细胞计数法获得的结果,均表明Au/Ag/rGO-5FU组合比纯5-氟尿嘧啶具有更强的抗癌作用和更高的药物稳定性。
