This study aims to synthesize barium and iron dual-doped titanium dioxide (TiBaFeO NC) using a green precipitation method with Psidium guajava leaf extract, targeting improved antimicrobial and anticancer efficacy. The synthesized nanocomposite was characterized by various analytical techniques. XRD confirmed the crystalline anatase phase of TiO2 and TiBaFeO NC, with average crystallite sizes of 40 and 37nm, respectively, suitable for biomedical applications. UV-Vis analysis showed a decrease in bandgap from 3.79eV for TiO2 to 3.67eV for TiBaFeO NC, indicating enhanced reactive oxygen species (ROS) generation potential. PL spectra exhibited green emissions at 520nm for TiO2 and 523nm for TiBaFeO NC, reflecting a higher oxygen vacancy defect density in the doped nanocomposite. Biological evaluations demonstrated that TiBaFeO NC exhibited superior antimicrobial activity against Gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis, Bacillus megaterium), Gram-negative bacteria (Shigella dysenteriae, Escherichia coli, Proteus vulgaris), and fungi (Candida albicans). Furthermore, TiBaFeO NC showed enhanced anticancer activity against human breast cancer cells (MDA-MB-231) with an IC50 of 9.8g/mL, outperforming TiO2. These results suggest that TiBaFeO NC is a promising nanocomposite for advanced biomedical applications, combining enhanced antimicrobial and anticancer properties through defect-mediated ROS generation. 2026 International Union of Biochemistry and Molecular Biology, Inc.
