Titanium Dioxide (TiO2)

Electrospun chitosan (Cs) nanofibers were sputtered with TiO2 particles by plasma-enhanced chemical vapor deposition using a planar magnetron device [132]. The physiochemical interaction of the Cs and Cs-TiO2 was studied computationally using the Gaussian software package, followed by experimentally examining the antibacterial properties of the materials. The results revealed that Cs-TiO2 behaves as a single composite unit by forming a C-O-C glycosidic bond in the glucose ring. The Cs-TiO2 composite had an improved structure and reactivity because of the reduced HUMO-LUMO energy gap, larger dipole moment, and lower ionization potential when compared to pure Cs. Finally, the Cs-TiO2 composites exhibited antibacterial activity, with inhibition zones approximately 11.5 mm in diameter.
