Abstract—Nanosized materials are attracting a great deal in
biological and pharmaceutical applications. Especially, metal oxide
nanoparticles are known to possess antibacterial properties. TiO2
nanoparticles, have become a new generation of advanced materials
due to their optical, dielectric, and photo-catalytic characteristics
from size quantization. These properties have been applied in
removing bacteria and harmful organic materials from water and air.
In this work, we investigated antimicrobial activity of synthesized
TiO2
nanoparticles by ultrasound method. The TiO2
nanoparticles
were characterized by X-ray diffraction, nano sizer and atomic force
microscopy analyses. The antibacterial effect of these obtained
nanoparticles was examined on E. coli (ATCC 8739), Staph.aureus
(ATCC 6538), P.aeruginosa (ATCC 9027), C.albicans (ATCC
36232) and B.subtilis (ATCC 6633). The synthesized TiO2
nanoparticles were found to be effective against these bacterias.
Based on this study, we may conclude that the synthesized by
ultrasound method TiO2
nanoparticles can be a good inorganic
antimicrobial agents.
