Background: In the current scenario, synthesis of nanoparticles (NPs) using environmentally benign methods has gained significant attention due to their facile processes, cost-effectiveness, and eco-friendly nature. Methods: present study, copper oxide (CuO NPs) were synthesized aqueous extract Coelastrella terrestris algae as a reducing, stabilizing, capping agent. The CuO NPs characterized by X-ray diffraction (XRD), UV-visible spectroscopy (UV-Vis), Fourier transform infrared (FTIR), dynamic light scattering (DLS), field emission scanning electron microscopy (FE-SEM) coupled with energy-dispersive (EDS). Results: XRD investigation revealed that biosynthesized nanocrystalline high-phase purity size in range 4.26 nm 28.51 nm. FTIR spectra confirmed existence secondary metabolites on surface NPs, characteristic Cu–O vibrations being identified around 600 cm − 1 , 496 440 . FE-SEM images predicted enhancement algal amount converted flattened rice-like structures into flower petal-like structures. Furthermore, degradation ability was investigated against Amido black 10B (AB10B) dye. results displayed optimal efficacy AB10B dye 94.19%, obtained at 6 pH, 50 ppm concentration dye, 0.05 g dosage 90 min pseudo-first-order rate constant 0.0296 CuO-1 through exhibited notable antibacterial S. aureus zone inhibition (ZOI) 22 mm P. aeruginosa ZOI 17 mm. Conclusion: Based findings this it can be concluded utilizing for presents promising solution addressing environmental contamination.
