Enriched biological activity of copper oxide nanoparticles derived from Aloe vera extract

Nanotechnology is an expanding field with significant potential to benefit society. This study focuses on the environmentally friendly synthesis of copper oxide nanoparticles (CuONPs) using Aloe vera leaf extract and explores their applications in the field of biomedicine. Aloe vera extracts were carefully evaluated and analyzed both qualitatively and quantitatively. The synthesized CuONPs derived from Aloe vera were thoroughly characterized using various techniques, including UV–Vis spectroscopy, FTIR microscopy, SEM, TEM, zeta potential, and histogram analysis with EDX. Furthermore, the biomedical applications of CuONPs were extensively examined. This involved assessing their efficacy against respiratory tract-causing microbes, evaluating in vitro antioxidant, antidiabetic, and anti-inflammatory activities, conducting MTT assays against L929 cell lines, and utilizing the AO/EtBr staining method. The results unequivocally demonstrated the exceptional potential of environmentally friendly CuONPs in various biomedical activities.
