The transition-metal dichalcogenides (TMDCs) like MoS and WS are a new and interesting class of materials and show considerable promise for use in a wide variety of fields, including nanomedicine for cancer. The eco-friendly, biodegradability, toxicity, and antimicrobial activity remain an open issue. Herein, we focused on the current demands of two dimensional (2D) TMDCs and produced high-quality, few-layered MoS nanosheets. Noble metal Ag incorporated into the 2D-CS/MoS NC by the liquid exfoliated process. The manufactured CS/MoS/Ag hybrid NC showed excellent antibacterial activity against two microorganisms such as Gram-positive (21, 27, and 33 mm) and Gram-negative bacteria (23, 30, and 39 mm). The CS/MoSAg hybrid NC was designed to have significant antibacterial activity against E.coli bacteria than S.aureus. Furthermore, the hybrid NC has a 74.18% cell inhibition against MCF-7 cancer cells. According to the literature relevant, it is the first extensive experimental analysis on the nano-bio interaction of 2D TMDCs nanomaterials in MCF-7 breast cancer cells.
过渡金属二硫属化物(TMDCs)如 MoS 和 WS 是一类新型且有趣的材料,在包括癌症纳米医学在内的各种领域都有很大的应用潜力。它们具有环保、可生物降解、低毒性和抗菌活性等优点。在此,我们专注于二维(2D)TMDCs 的当前需求,并制备了高质量的少层 MoS 纳米片。通过液相剥离工艺将贵金属 Ag 掺入到 2D-CS/MoS NC 中。所制备的 CS/MoS/Ag 杂化 NC 对两种微生物(革兰氏阳性菌(21、27 和 33mm)和革兰氏阴性菌(23、30 和 39mm))表现出优异的抗菌活性。CS/MoSAg 杂化 NC 对大肠杆菌的抗菌活性明显高于金黄色葡萄球菌。此外,杂化 NC 对 MCF-7 癌细胞的细胞抑制率为 74.18%。根据相关文献,这是首次对 2D TMDCs 纳米材料在 MCF-7 乳腺癌细胞中的纳米-生物相互作用进行广泛的实验分析。
