Synergistic antibacterial activity of barium doped TiO₂nanoclusters synthesized by microwave processing

Dye degradation performance, bactericidal behavior and molecular docking analysis of Cu-doped TiO2 nanoparticles

“…It can be seen that the energy decreases with an increase in dopant concentration which is well corroborated by reported literature. 48,59,66 Doping with a transition metal such as Cu can induce new electronic phases in actual band gap which suggests that e À are excited by defect state of TiO 2 conduction band with less photon energy. 59 Drop in band gap energy with an increase in Cu concentration is attributed to Cu 2+ ions that intercalated between host lattices of TiO 2 and generated oxygen vacancies due to charge compensation effect.…”

Engineering of magnetically separable ZnFe2O4@ TiO2 nanofibers for dye-sensitized solar cells and removal of pollutant from water

“…As shown in Fig. 5, two characteristics absorption peaks at about 466 cm −1 and 1100 cm −1 are belongs to Ti-O stretching [33,34]. Furthermore, the absorption peaks at around 550 cm −1 can be assigned to tetrahedral Zn-O bonds while absorption peak at around 415 cm −1 can be associated to octahedral Fe-O bonds [35,36].…”

Bioactive silver phosphate/polyindole nanocomposites

“…The difference in antibacterial potency demonstrated earlier may be accounted for by the dissimilar cellular structures of S. aureus and E. coli, but the varied inhibition efficiency among composites indicated that parameters other than physiological differences between bacteria might be important. The means by which cellular damage by ROS 74 and non-ROS include the dissolution of cations, 7 internalization of nanostructures, 7 cell membrane disintegration via protein leakage, 75 membrane permeability changes 60 may explain the antibacterial activity of the nanostructured materials. We examined ROS generation from the nanostructures extracellularly and intracellularly.…”
