Abstract

Nanotechnology (NT) and nanoparticles (NPs) have left a huge impact on every field of science today, but they have shown tremendous importance in the fields of cosmetics and environmental cleanup. NPs with photocatalytic effects have shown positive responses in wastewater treatment, cosmetics, and the biomedical field. The chemically synthesized TiO₂ nanoparticles (TiO₂ NPs) utilize hazardous chemicals to obtain the desired-shaped TiO₂. So, microbial-based synthesis of TiO₂ NPs has gained popularity due to its eco-friendly nature, biocompatibility, etc. Being NPs, TiO₂ NPs have a high surface area-to-volume ratio in addition to their photocatalytic degradation nature. In the present review, the authors have emphasized the microbial (algae, bacterial, fungi, and virus-mediated) synthesis of TiO₂ NPs. Furthermore, authors have exhibited the importance of TiO₂ NPs in the food sector, automobile, aerospace, medical, and environmental cleanup.

Keywords: dye removal; microbial synthesis; photocatalytic degradation; titanium dioxide; waste water.
