Abstract

Abstract Bacterial cellulose (BC) is a microbiologically produced cellulose with high purity and excellent biocompatibility, allowing it to be used alone or in combination with other materials, including polymers and nanoparticles. This study was conducted to incorporate silver nanoparticles (AgNPs) into a BC matrix using simple and environmentally friendly methods in order to create a composite with superior industrial properties. The fabricated composites were characterized with Fourier transform infrared, X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray (EDX), while the thermal stability was investigated by thermogravimetric analysis. The antimicrobial activity of the composites was determined by observing the formation of an inhibition zone during the incubation of Staphylococcus aureus (gram-positive) and Escherichia coli (gram-negative). The SEM, EDX, and XRD analysis confirmed the presence of AgNPs. The composites also exhibit excellent thermal stability and significant antimicrobial activity against S. aureus and E. coli.

细菌纤维素/银纳米粒子复合材料的绿色合成方法及表征

细菌纤维素(BC)是一种微生物生产的纤维素，具有高纯度和优异的生物相容性，使其可以单独使用或与其他材料(包括聚合物和纳米颗粒)结合使用。本研究采用简单环保的方法将银纳米颗粒(AgNPs)掺入BC基质中，以制备具有优异工业性能的复合材料。采用傅里叶变换红外、x射线衍射(XRD)、扫描电镜(SEM)和能量色散x射线(EDX)对复合材料进行了表征，并通过热重分析考察了复合材料的热稳定性。通过观察金黄色葡萄球菌(革兰氏阳性)和大肠杆菌(革兰氏阴性)在培养过程中形成的抑制带来确定复合材料的抗菌活性。SEM, EDX和XRD分析证实了AgNPs的存在。复合材料还表现出优异的热稳定性和对金黄色葡萄球菌和大肠杆菌的显著抗菌活性。

期刊介绍： Green Processing and Synthesis is a bimonthly, peer-reviewed journal that provides up-to-date research both on fundamental as well as applied aspects of innovative green process development and chemical synthesis, giving an appropriate share to industrial views. The contributions are cutting edge, high-impact, authoritative, and provide both pros and cons of potential technologies. Green Processing and Synthesis provides a platform for scientists and engineers, especially chemists and chemical engineers, but is also open for interdisciplinary research from other areas such as physics, materials science, or catalysis.
