Polysaccharides that show finest bioactivities and physicochemical properties are always promising for bionanoscience applications. Mauran is such a macromolecule extracted from halophilic bacterium, Halomonas maura for biotechnology and nanoscience applications. Antioxidant properties of MR/CH nanoparticles were studied using biochemical assays to prove the versatility of these test nanoparticles for biomedical applications. Here, we demonstrate the prospects of extremophilic polysaccharide, mauran based nanoparticles for scavenging reactive oxygen species in both in vitro and ex vivo conditions. 5-fluorouracil loaded MR/CH nanoparticles were tested for anticancer proliferation and compared their therapeutic efficiency using breast adenocarcinoma and glioma cells. Fluorescently labeled nanoparticles were employed to show the cellular uptake of these nanocarriers using confocal microscopic imaging and flow cytometry.
具有最佳生物活性和物理化学性质的多糖一直是生物纳米科学应用的热门选择。从嗜盐菌盐单胞菌中提取的 Mauran 就是这样一种用于生物技术和纳米科学应用的大分子。使用生化分析来研究 MR/CH 纳米粒子的抗氧化特性,以证明这些测试纳米粒子在生物医学应用中的多功能性。在这里,我们展示了基于极端嗜热多糖 Mauran 的纳米粒子在体外和体内条件下清除活性氧的前景。负载 5-氟尿嘧啶的 MR/CH 纳米粒子用于测试抗癌增殖,并使用乳腺癌腺癌细胞和神经胶质瘤细胞比较它们的治疗效率。使用荧光标记的纳米粒子通过共聚焦显微镜成像和流式细胞术显示这些纳米载体的细胞摄取。
