The novelty of this present work is to investigate the anti-bacterial and anti-fungal activity of the green synthesized titanium dioxide (TiO2) nanoparticles using leaf extract of Mentha arvensis, titanium tetraisopropoxide act as the precursor and leaf extract act as the reducing agent. Synthesized nanoparticles were characterized by using X-ray diffraction, UV–Visible absorbance spectroscopy, Fourier transform infrared spectroscopy and scanning electron microscopy methods. The X-ray diffraction study of the synthesized nanoparticles shows the crystalline structure and the incidence of peaks at 25.27° corresponds to 110 anatase form. Scanning electron microscope study revealed that the synthesized nanoparticle was spherical in shape and the average size of the synthesized nanoparticles was found to be the range of 20–70 nm. Green synthesized TiO2nanoparticle exhibited interesting antibacterial and antifungal activity against selected microorganism.
