Abstract
This study addresses the pressing concern of dye effluent contamination in water bodies and proposes a multifaceted solution through the synthesis and application of Manganese cobalt oxide (MnCo2O4) nanoparticles. The nanoparticles were prepared hydrothermally using acetate precursors, and their composition was carefully confirmed by XRD, FTIR, UV-DRS, FESEM, and EDX studies. The prepared MnCo2O4 nanoparticles, when exposed to the best-suited conditions (20 mL of dye solution containing 2.5 mg of MnCo2O4 NP kept at direct sunlight for 24 h, reaction time), exhibited remarkable efficiency in completely breaking down inorganic dyes, with removal percentages of 78.8 % for Methyl blue (MB) and 97.6 % for Congo red (CR). Notably, the synthesized MnCo2O4 nanoparticles display strong antibacterial capabilities against multidrug-resistant bacteria and considerable anticancer effects on the cervical cancer cell line (HeLa), as verified by the MTT assay. This comprehensive investigation positions the MnCo2O4 nanoparticle as a promising candidate for efficient wastewater treatment, a robust antibacterial agent, and a potential therapeutic agent against cervical cancer, highlighting its diverse and impactful applications.
