For the first time, copper oxide (CuO) nanostructures were synthesized through a new green route using the leaf extract of S. glauca and characterized. The XRD pattern of CuO disclosed diffraction peaks correspond to monoclinic crystal structured CuO. The SEM and HR-TEM images demonstrated the presence of CuO nanostructures. The detected Cu and O elements through the EDAX analysis reveal the pristine nature of the hierarchical CuO nanostructures. Hence, this work complete that the potential bactericidal activity exhibited by CuO nanostructures against Gram negative E. coli (MTCC 1698) bacterial strain with zone of inhibition of 28 mm.

Simarouba glauca叶提取物绿色合成具有杀菌活性的CuO纳米颗粒

首次使用新的绿色途径，用青冈叶提取物合成了氧化铜（CuO）纳米结构并进行了表征。公开的CuO的衍射峰的XRD图谱对应于单斜晶体结构的CuO。SEM和HR-TEM图像证明了CuO纳米结构的存在。通过EDAX分析检测到的Cu和O元素揭示了层状CuO纳米结构的原始性质。因此，这项工作完成了CuO纳米结构对革兰氏阴性大肠杆菌（MTCC 1698）细菌菌株具有28 mm抑制区的潜在杀菌活性。
