This growing challenge highlights the urgent need for advanced nano-based antibacterial materials capable of overcoming resistance and providing broad-spectrum protection. In this study, magnesium fluoride (MgF2) NPs and Chitosan modified MgF2 (MgF2-Cs) were synthesized via a facile wet-chemical route and characterized to evaluate their structural, surface, and antibacterial properties. XRD confirmed the formation of tetragonal MgF2 with crystallite sizes of 29nm for MgF2 and 22nm for MgF?Cs, the reduction attributed to Cs-induced surface modification. FTIR, PL, and XPS analyses verified successful Cs incorporation through the presence of OH, NH?, CN, and OC=O functional groups and the preservation of the MgF2 lattice. DLS further supported increased hydrodynamic size upon polymer coating. PL analysis showed enhanced blue-green emission around 497nm in MgF2Cs, suggesting increased defect density and corresponding ROS-generation ability. Antibacterial activity against Gram-positive: S. aureus, S. pneumoniae and Gram-negative: K. pneumoniae, S. dysenteriae bacteria demonstrated significantly improved inhibition for MgF2Cs, with zone diameters of 1521mm, surpassing MgF2 (1216mm) and Cs (1115mm. The MIC and MBC values for MgF?-Cs against K. pneumoniae were determined to be 0.6mgmL?1 and 0.9mgmL?1, respectively. The enhanced antibacterial performance is attributed to synergistic effects of defect-mediated ROS production and Csbacteria electrostatic interactions. 2026 Elsevier B.V.
