Metal oxide nanoparticles (NPs) have experienced flourishing development in diverse fields, such as industry, medicine and environmental science, as a result of the development of nanotechnology. In this realm, titanium dioxide nanoparticles (TiO₂ NPs) are favored due to their broad applications and potential in nanomedicine. Very recently, more attention has been given to green, or biological, synthesis of these nanoparticles, due to the significant advantages that they present, such as reduced toxicity, less dependence on toxic chemical in the synthetic process, eco-friendliness, and lower cost as well as shape and size control, when compared with traditional synthetic methods. Traditional physical or chemical methods, however, suffer from high energy consumption and pollution of hazardous chemicals. Conversely, bio-mediated synthesis can offer a much safer and sustainable alternative for the production of TiO₂ NPs. This review details the bio-based synthesis of TiO₂ NPs and their diverse biomedical applications-raging from the antibacterial and antifungal properties to anticancer and antiviral therapies-and discusses the impact of such developments on the future of health care and environmental technologies.
