Green synthesis is a technique for the fabrication of\ nanoparticles\ (NPs) that is easy, eco-friendly, and emergent. It is currently garnering the attention of the scientific community worldwide since it is non-toxic, inexpensive, and reliable, and it takes place under ambient conditions. This research aimed to synthesize green N-doped\ titanium dioxide nanoparticles\ (N-TiO2) and analyze their antimicrobial, anti-oxidant activity, and\ dielectric properties. A leaf extract of\ Tamarix\ sp. was used in a single step at\ room temperature\ to fabricate N-TiO2nanoparticles\ with an average particle size of 26.5 nm. They were subsequently characterized by certain methods like Ultra Violet-Visible spectroscopy,\ Transmission Electron Microscopy,\ Field Emission Scanning Electron Microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Fourier Transform Infra-Red Spectroscopy, etc. Moreover, the efficiency of the synthesized\ nanoparticles\ as antimicrobial agents was investigated against\ Bacillus subtilis,\ Escherichia coli\ and\ Aspergillus niger. Using 2, 2-diphenyl-1-picrylhydrazyl hydrate (DPPH), the antioxidant activity of synthesized N-TiO2nanoparticles\ (NPs) was evaluated. UV{\textendash}visible\ spectrophotometry\ was used to monitor the radical-scavenging activity of N-TiO2\ NPs. The\ dielectric properties\ were examined with the help of impedence analyzer and we observed high\ dielectric constant\ and very low tangent loss.
