The Effect of Temperature Treatment TiO2 Nanoparticles on Antibacterial Properties
Abstract
The synthesis of TiO2 nanoparticles (NPs) under various temperature treatments was described and TiO2 NPs
was subsequently tested as an antibacterial agent. Scanning electron microscopy (SEM), Raman
spectroscopy, Dynamic light scattering (DLS) were used to confirm structure of TiO2 NPs and detect
differences between individual batches treated with different temperature. Antibacterial properties were tested
on Escherichia coli (E. coli). TiO2 NPs as photocatalyst was incubated with bacterial cells under ambient light.
Changes in temperature treatment can affect diameter size and crystal structure of TiO2 NPs as well as its
antibacterial properties.
