摘要

Co-precipitation-synthesized multifunctional nanoparticles offer a sustainable strategy for advanced cancer therapy by enabling targeted action, reducing side effects, and improving therapeutic efficacy while maintaining biocompatibility. In this study, curcumin, barium, and cobalt-doped TiO₂ nanoparticles (TiO₂BaCoCur) were synthesized via a co-precipitation route and evaluated for antibacterial, antifungal, and anticancer activities. X-ray diffraction confirmed the anatase phase of TiO₂ along with cubic Ba–Co phases and crystalline curcumin. FTIR and XPS analyses verified the presence and bonding states of Ti, Ba, Co, C, and O, confirming successful doping and surface functionalization. UV–Vis absorption studies revealed a reduced band gap of 3.3 eV, while photoluminescence analysis indicated enhanced surface defects and trap states that can promote reactive oxygen species generation. SEM and TEM analyses showed near-spherical nanoparticles with an average size of 45 nm. TiO₂BaCoCur exhibited strong antifungal activity against C. albicans and effective antibacterial activity against S. aureus, S. pneumoniae, B. megaterium, P. aeruginosa, P. vulgaris, and V. cholerae. The nanoparticles demonstrated significant cytotoxicity toward HCT-116 colon cancer cells with an IC₅₀ of ~ 10 µg/mL, while showing negligible toxicity toward L929 fibroblast cells, indicating excellent biocompatibility. An XGBoost-based machine learning model established clear structure–activity relationships, identifying particle size and band gap as key determinants of bioactivity. The strong agreement between experimental and predicted results highlights the potential of this integrated experimental and ML approach for accelerating the design of TiO₂-based nanomaterials for biomedical applications.
