Multidrug resistance developed by many microorganisms lead to search for the novel remedy to treat pathogens. Many metals and metal oxide nanoparticles such as silver, zinc oxide, copper, copper oxide and titanium dioxide demonstrated antimicrobial properties since ancient times. Nano particles of titanium dioxide find applications in the field of catalysis, cosmetics, medicines, paints, coatings, solar devices etc. In this review, the antimicrobial properties of TiO2 nanoparticles synthesized by chemical and green route are summarized. TiO2 nanoparticles found to be potential antimicrobial agents against gram positive and gram negative bacteria. These nano particles are widely used in the field of dentistry to treat infections caused by Streptococcus mutans commonly found pathogen in oral cavity. In the field of food packaging these nanoparticles are effective against Escherichia coli. TiO2 nano particles act via release of anti oxidatns that cause damage to microbial cells. TiO2 nanoparticles in various forms i.e nanoparticles suspension, colloidal form, coatings or incorporated in fabric are effective against microorganisms. Titanium dioxide nano particles are low cost, non toxic , stable and effective against microorganisms. They are widely used in the field of medicine, textile and food packaging.
