Cistus incanus leaf extract was used to biologically synthesize Copper oxide nanoparticles (CuO NPs). The characteristic UV-vis spectral band of CuO NPs found at 290 nm revealed the successful formation of CuO NPs. By the analysis of TEM and SEM, it is confirmed that the obtained CuO NPs were in spherical structure. By the analysis of Fourier transform infrared (FTIR) spectroscopy, it is evident that the absorption peak was situated at a position of about 480 cm of wavenumber, which is typically considered as an extremely pure CuO NPs. The images of Transmission Electron Microscopy exhibited that the formed CuO NPs were in the size of about 15-25 nm and were relatively uniform in distribution. When related with the treatment of nanomaterials only, the synergistic interaction among CuO NPs and oxidative stress conditions considerably decreased the cardiac-related function catalogs, which includes pathological progressions of myocardium along with an obvious rise in the levels of creatine kinase-MB and cardiac troponin I. When compared to the void reaction of micro-CuO and cardiac operations in alloxan-injected rats, aggravation in the conditions of oxidative stress could be playing a significant part in the heart injury after dual exposing CuO NPs and alloxan. By these results, it is confirmed that the conditions of oxidative stress improved the contrary effects of CuO NPs to the heart, signifying that the utilization of nanomaterials in conditions of stress such as, in the delivery of drug, required to be cautiously monitored.
乳香树叶提取物被用于生物合成氧化铜纳米粒子(CuO NPs)。CuO NPs 的特征紫外-可见光谱带在 290nm 处被发现,表明 CuO NPs 的成功形成。通过 TEM 和 SEM 的分析,证实了所获得的 CuO NPs 呈球形结构。通过傅里叶变换红外(FTIR)光谱分析,明显看出吸收峰位于约 480cm-1 的波数位置,通常被认为是极其纯净的 CuO NPs。透射电子显微镜的图像表明,形成的 CuO NPs 的尺寸约为 15-25nm,分布相对均匀。仅与纳米材料的处理相关,CuO NPs 与氧化应激条件之间的协同相互作用大大降低了与心脏相关的功能目录,包括心肌的病理进展以及肌酸激酶-MB 和心肌肌钙蛋白 I 水平的明显升高。与微-CuO 的空反应和在链脲佐菌素注射大鼠中的心脏手术相比,氧化应激条件的恶化可能在双重暴露 CuO NPs 和链脲佐菌素后对心脏造成的损伤中发挥重要作用。根据这些结果,可以确认氧化应激条件改善了 CuO NPs 对心脏的相反作用,这表明在诸如药物输送等应激条件下使用纳米材料需要谨慎监测。
