Abstract

This paper presents a pioneering investigation of synthesizing Ag-NPs using Macassar Ebony seed (MES) extract. The bioactive metabolites in the MES extract were essential in reducing silver (Ag) ions, forming MES-Ag-NPs. The biosynthesized MES-Ag-NPs were characterized using several techniques, including UV–visible, DLS, XRD, FT-IR, and TEM. The MES-Ag-NPs have a zeta potential of − 33.9 mV, which defines their stability. The XRD diffractogram exhibited peaks at 2θ values of 38.07°, 44.27°, 64.62°, and 77.57°, which correspond to the (111), (200), (220), and (311) crystallographic planes of cubic Ag crystal, respectively. The TEM image revealed that the MES-Ag-NPs exhibited multi-shapes and had an average size of 48.76 nm. When used as catalysts to degrade methylene blue (MB), MES-Ag-NPs demonstrated a degradation efficiency of more than 80% in just 10 min. Besides, the MES-Ag-NPs had a ZOI of 10.83 ± 1.17 mm against Staphylococcus aureus and 10.67 ± 1.19 mm against Escherichia coli, which shows that they might be helpful as an antibacterial agent. The findings of this study shed light on the potential advantages that MES-based Ag-NPs may bring to the medical and environmental remediation fields.

具有催化和抗菌活性的马卡萨乌木种子提取物介导的银纳米粒子的生物合成与表征
本文介绍了利用马卡萨乌木籽(MES)提取物合成 Ag-NPs 的开创性研究。马卡萨尔乌木籽提取物中的生物活性代谢物对还原银(Ag)离子、形成马卡萨尔乌木籽-Ag-NPs至关重要。生物合成的 MES-Ag-NPs 采用多种技术进行表征,包括紫外可见光、DLS、XRD、傅立叶变换红外光谱和 TEM。MES-Ag-NPs 的 zeta 电位为 - 33.9 mV,这决定了其稳定性。XRD 衍射图显示,在 2θ 值为 38.07°、44.27°、64.62° 和 77.57°处出现了峰值,分别对应于立方银晶体的 (111)、(200)、(220) 和 (311) 晶面。TEM 图像显示,MES-Ag-NPs 具有多种形状,平均尺寸为 48.76 nm。当 MES-Ag-NPs 用作催化剂降解亚甲基蓝(MB)时,其降解效率在短短 10 分钟内就超过了 80%。此外,MES-Ag-NPs 对金黄色葡萄球菌的 ZOI 为 10.83 ± 1.17 mm,对大肠杆菌的 ZOI 为 10.67 ± 1.19 mm,这表明它们可以作为一种抗菌剂。本研究的发现揭示了基于 MES 的 Ag-NPs 在医疗和环境修复领域可能带来的潜在优势。

期刊介绍: Journal of Inorganic and Organometallic Polymers and Materials [JIOP or JIOPM] is a comprehensive resource for reports on the latest theoretical and experimental research. This bimonthly journal encompasses a broad range of synthetic and natural substances which contain main group, transition, and inner transition elements. The publication includes fully peer-reviewed original papers and shorter communications, as well as topical review papers that address the synthesis, characterization, evaluation, and phenomena of inorganic and organometallic polymers, materials, and supramolecular systems.
