Biosynthesis of copper oxide nanoparticles and their potential synergistic effect on alloxan induced oxidative stress conditions during cardiac injury in Sprague–Dawley rats

Abstract

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−1 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.
