The prevalence of numerous infectious diseases has emerged as a grave concern within the realm of healthcare. Currently, the issue of antibiotic resistance is compelling scientists to explore novel treatment approaches. To combat these infectious diseases, various treatment methods have been developed, harnessing cutting-edge disinfecting nanomaterials. Among the range of metallic nanoparticles employed in medicine, silver nanoparticles (AgNPs) stand out as both highly popular and well-suited for the task. They find extensive utility in cancer diagnosis and therapies and as effective antibacterial agents. The interaction between silver and bacterial cells induces significant structural and morphological alterations, ultimately leading to cell demise. In this study, nanoparticles based on silver and bambusuril[6] (BU[6]) were developed for the first time. These NPs can be used for different biomedical purposes. A simple, single-step, and effective synthesis method was employed to produce bambusuril[6]-protected silver chloride nanoparticles (BU[6]-Ag/AgCl NPs) through the complexation of BU[6] with silver nitrate. The NPs were characterized using X-ray phase analysis (XPS), infrared spectroscopy (IR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). When the SEM images were examined, it was seen that the synthesized BU[6]-Ag/AgCl NPs were distributed with homogeneous sizes, and the synthesized NPs were mostly spherical and cubic. The EDS spectra of BU[6]-Ag/AgCl NPs demonstrated the presence of Ag, Cl, and all expected elements. BU[6]-Ag/AgCl NPs showed high antibacterial activity against both and bacteria.
众多传染病的流行已成为医疗保健领域的一个严重问题。目前,抗生素耐药性问题迫使科学家探索新的治疗方法。为了对抗这些传染病,已经开发了各种治疗方法,利用了先进的消毒纳米材料。在医学中使用的各种金属纳米粒子中,银纳米粒子(AgNPs)既非常受欢迎,又非常适合这项任务。它们在癌症诊断和治疗以及作为有效的抗菌剂方面有广泛的应用。银与细菌细胞之间的相互作用会引起显著的结构和形态改变,最终导致细胞死亡。在这项研究中,首次开发了基于银和杯[6](BU[6])的纳米粒子。这些 NPs 可用于不同的生物医学用途。通过硝酸银与杯[6]的络合,采用简单、单步、有效的合成方法,制备了杯[6]保护的氯化银纳米粒子(BU[6]-Ag/AgCl NPs)。采用 X 射线相分析(XPS)、红外光谱(IR)、热重分析(TGA)、扫描电子显微镜(SEM)和能谱(EDS)对 NPs 进行了表征。当检查 SEM 图像时,发现合成的 BU[6]-Ag/AgCl NPs 分布均匀,合成的 NPs 大多呈球形和立方体形。BU[6]-Ag/AgCl NPs 的 EDS 图谱表明存在 Ag、Cl 和所有预期的元素。BU[6]-Ag/AgCl NPs 对 和 细菌均表现出很高的抗菌活性。
