⑶采用低温微波水热法合成氧化镁纳米线。研究了MgO纳米线的抗菌性能。这种新方法为大规模制备氧化镁纳米线和抗菌剂提供了直接途径。采用一种新的简单易行的反应方法，成功地合成了直径为6 nm，长度为10 μm的大尺寸一维氧化镁（MgO）纳米线。通过微波水热方法在180 °C的低温生长30分钟进行该生产。采用X射线衍射（X-ray）、傅里叶变换红外光谱（FTIR）、场发射扫描电子显微镜（FE-SEM）、透射电子显微镜（TEM）、选区电子衍射（SAED）和能量色散X射线（EDS）等手段对MgO纳米线的结构进行了表征。详细测试了MgO纳米线在固体介质中对革兰氏阴性菌和革兰氏阳性菌的抗菌行为。结果表明，MgO纳米线对大肠杆菌和芽孢杆菌具有一定的抑菌活性，其抑菌活性随MgO纳米线浓度的增加而增强。此外，一维MgO纳米线的存在具有高的抗菌功效，并破坏细菌的膜壁。最后，本研究提供了前景，开发超细纳米器件利用氧化镁纳米线和实现其有用的潜力，在生物控制。
► Low temperature microwave hydrothermal method is developed to synthesize MgO nanowires. ► The antibacterial properties of MgO nanowires have been examined. ► This novel method serve a direct route for mass production of MgO nanowires and antibacterial agents. Large-scale one-dimensional magnesium oxide (MgO) nanowires with diameters of 6 nm and lengths of 10 μm have been successfully synthesized by a new facile and simple reaction. This production was performed via a microwave hydrothermal approach at low temperature growth of 180 °C for 30 min. The structure of as synthesized MgO nanowires were investigated by means of X-ray diffraction (X-ray), Fourier Transformation Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FE-SEM), Transmission Electron Microscopy (TEM), Selected Area Electron Diffraction (SAED) and Energy Dispersive X-ray (EDS). The antibacterial behavior of MgO nanowires concentration in solid media against Gram negative and Gram positive for different bacteria has been tested in details. The results show that the MgO nanowires have bacteriostatic activity against Escherichia coli and Bacillus sp. The antibacterial activity increases with increasing MgO nanowires concentration. Furthermore, the presence of one-dimensional MgO nanowires has high antibacterial efficacy and damages the membrane wall of bacteria. Finally, this study offered the prospect of developing ultrafine nanoscale devices utilizing MgO nanowires and implementing their useful potential in biological control.
