In this work, copper oxide nanoparticles (CuO NPs) were synthesized using a biological method. These particles have received increasing attention compared to other metal oxides due to their unique properties and multiple applications. Plant-based nanoparticle synthesis has gained widespread interest from researchers due to its simplicity and environmentally friendly approach. The biosynthesis of CuO NPs involved the use of ginger root extract, which acts as both a reducing agent and stabilizer. The use of plant extract in the formation of nanomaterials is a non-toxic, low-cost, and environmentally friendly method. The prepared particles were analyzed using several analytical techniques, including UV–Vis spectroscopy, FTIR spectroscopy, SEM, and XRD. SEM examination results, which provide morphological information, showed that the prepared particles were spherical with an average size ranging from 15 to 30 nm. In this study, CuO particles were studied to evaluate their antioxidant activity by testing their ability to inhibit DPPH free radicals. The results were monitored using UV–Vis spectroscopy. The results demonstrated that the bio-prepared CuO particles possessed significant antioxidant activity.
