Implication

Randomized trial shows photocatalytic antibacterial activity of TiO2 nanoparticles against multidrug-resistant bacteria, suggesting effective treatment options.

Key Points

  • This research aims to synthesize titanium dioxide nanoparticles and evaluate their antibacterial properties against multidrug-resistant bacteria.
  • Manufactured TiO2 nanoparticles using sol-gel technique with titanium tetraisopropoxide as a precursor.
  • Characterized nanoparticles with XRD, FTIR, UV-Vis, SEM, and TEM techniques.
  • Tested antibacterial activity against MRSA, E. coli, P. aeruginosa, and K. pneumoniae under UV irradiation.
  • TiO2 nanoparticles showed a mean crystalline size of 18.4 nm with a pure anatase phase as confirmed by XRD.
  • Antibacterial tests revealed a maximum inhibition zone of 27.8 mm against E. coli and 25.4 mm against MRSA at a concentration of 400 µg/ml.
