Visible Light Photocatalyst Anatase Phased TiO2 Nanoparticles for Enhanced Antibacterial Performance
This study reports the development of anatase TiO 2 synthesized by facile photon-induced method (PIM) at various reaction times of 6 days, 8 days, 10-day samples. The 10 days TiO 2 sample shows stable anatase phase, whereas 100% rutile phase at the same temperature was observed for standard TiO 2 ....

Summary: | This study reports the development of anatase TiO
2
synthesized by facile photon-induced method (PIM) at various reaction times of 6 days, 8 days, 10-day samples. The 10 days TiO
2
sample shows stable anatase phase, whereas 100% rutile phase at the same temperature was observed for standard TiO
2
. Mainly, the PIM was used to tuning the properties of visible light absorbance TiO
2
photocatalyst used for improving antibacterial performance. The antibacterial activity of TiO
2
against
Staphylococcus aureus
and
Escherichia coli
was determined by the agar disc diffusion method. Anatase TiO
2
nanoparticles demonstrated excellent antibacterial activity against extracellular
S. aureus
with 80% and
E. coli
with 82% killing efficacy at concentrations as low as 100 μg/mL, which is 100% faster than the standard and other pure TiO
2
reported earlier. The obtained undoped anatase Titania with enhanced chemical reactivity has great potential for antibacterial properties. Moreover, the smaller crystallite size (25 nm) and narrowing bandgap (2.96 eV) TiO
2
nanoparticles were more effective in killing bacteria compared with standard TiO
2
. Therefore, this work indicated that anatase phased TiO
2
under visible light absorbance has good potential with excellent clinical applications. |
