Hydrothermal synthesis of pure and bio modified TiO2: Characterization, evaluation of antibacterial activity against gram positive and gram negative bacteria and anticancer activity against KB Oral cancer cell line

Titanium dioxide nanoparticles were found to be good anticancer and antibacterial agents. In this
study, the antibacterial and anticancer activities of pure TiO , turmeric, ginger and garlic modified TiO
nanoparticles were investigated. X-ray diffraction (XRD), Transmission electron microscopy (TEM),
Fourier transform infrared spectroscopy (FTIR) and UV–visible spectroscopy were used to analyze the
samples. Antibacterial activities were performed against five bacterial strains namely Escherichia coli,
Klebsiella pneumonia, Pseudomonas aeruoginosa, Staphylococcus aureus and Streptococcus mutans. The
modified TiO nanoparticles exhibited enhanced antibacterial activity when compared with pure TiOsamples and anticancer activities for the samples were performed in KB Oral cancer cell line. Theresults of the modified TiO NPs indicate a greater efficacy on anticancer and antibacterial properties
compared to the pure TiO NPs.
