Abstract

Antimicrobial textiles are crucial in various industries for combating contamination and improving hygiene. Copper's potent antimicrobial properties enhance infection control in medical fabrics. This study aims to synthesize copper in the form of nanoparticles CuNPs using Curcuma aromatica, to provide an effective, eco-friendly solution for antimicrobial medical textiles. The powder of the rhizome of Curcuma aromatica was boiled in sterile distilled water and the extract was used in the synthesis of CuNPs. The resulting CuNPs were characterized by UV–Vis spectroscopy, SEM, FTIR analysis, and XRD. The antibacterial efficacy of the synthesized CuNPs was tested against Staphylococcus aureus and Escherichia coli using the well diffusion method. The Cotton fabrics was embedded with synthesized CuNPs and again evaluated for its anti-bacterial property. The UV–VIS Spectroscopy showed absorption peaks above 554 nm due to the plasmon resonance of CuNPs. The size range of CuNPs was from 54 to 69 nm which was confirmed by SEM. FTIR analysis indicated the presence of various organic molecules associated with CuNPs. XRD analysis revealed the face-centered cubic crystal structure of the CuNPs. The CuNPs and CuNPs embedded cotton fabrics exhibited significant antibacterial activity against both Staphylococcus aureus and Escherichia coli. These findings support the use of Curcuma aromatica as a suitable source for CuNP synthesis and emphasize the significance of CuNPs in the development of effective antimicrobial fabrics for medical applications.

利用莪术植物合成纳米铜粒子及其在医用织物抗菌活性中的应用

抗菌纺织品在各行各业中对于抗污染和改善卫生状况至关重要。铜具有强大的抗菌特性，可加强医用织物的感染控制。本研究旨在利用莪术合成纳米颗粒 CuNPs 形式的铜，为抗菌医用纺织品提供一种有效、环保的解决方案。莪术根茎粉末在无菌蒸馏水中煮沸，提取物用于合成 CuNPs。紫外可见光谱、扫描电镜、傅立叶变换红外光谱和 X 射线衍射对所制备的 CuNPs 进行了表征。采用井扩散法测试了合成的 CuNPs 对金黄色葡萄球菌和大肠杆菌的抗菌效果。将合成的 CuNPs 嵌入棉织物后，再次对其抗菌性能进行了评估。紫外-可见光谱显示，由于 CuNPs 的等离子共振，在 554 纳米以上出现了吸收峰。CuNPs 的尺寸范围为 54 至 69 nm，这已被扫描电镜证实。傅立叶变换红外分析表明，CuNPs 中含有各种有机分子。XRD 分析表明 CuNPs 具有面心立方晶体结构。CuNPs 和嵌入 CuNPs 的棉织物对金黄色葡萄球菌和大肠杆菌都具有显著的抗菌活性。这些研究结果支持使用莪术作为合成 CuNP 的合适来源，并强调了 CuNPs 在开发医疗应用的有效抗菌织物方面的重要意义。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
