Abstract：
Nanoparticles have recently gained interest as an anti-bacterial agent due to their large surface area/volume ratio and potential to compromise the integrity of bacterial cell membranes. Due to its versatility and anti-bacterial activity, graphene-based materials have drawn significant interest in biomedical applications. One of the greatest threats to life in the modern technological era is the pervasiveness of infectious diseases since bacteria cells are constantly updating themselves to resist antibiotics. In this presented study, GO-Se nanocomposite has been synthesized using polymer solution via a simple dispersion method. The structural and physicochemical properties of nanocomposite were investigated in detail. Staphylococcus aureus, Proteus vulgaris, and Bacillus subtilis bacterial strains were employed to study the anti-bacterial activity of GO-Se nanocomposite. The results show that the synthesized nanocomposites have good efficacy as an anti-bacterial agent. UV-vis spectroscopy, FTIR spectroscopy, HRTEM, XPS, and Raman spectroscopy were used to analyze the as-prepared GO and GO-Se nanocomposite.
摘要：
纳米颗粒由于其大的表面积/体积比和损害细菌细胞膜完整性的潜力而最近作为抗菌剂获得了兴趣。由于其多功能性和抗菌活性，基于石墨烯的材料在生物医学应用中引起了极大的兴趣。在现代技术时代，对生命的最大威胁之一是传染病的普遍性，因为细菌细胞不断更新自己以抵抗抗生素。在这项研究中，GO-Se纳米复合材料已使用聚合物溶液通过简单的分散方法合成。详细研究了纳米复合材料的结构和理化性质。金黄色葡萄球菌,普通变形杆菌,和枯草芽孢杆菌菌株用于研究GO-Se纳米复合材料的抗菌活性。结果表明，合成的纳米复合材料具有良好的抗菌剂功效。紫外-可见光谱，FTIR光谱,HRTEM,XPS,并利用拉曼光谱对制备的GO和GO-Se纳米复合材料进行了分析。
