Abstract: Pure and nitrogen doped titanium dioxide nanoparticles were synthesized using a bio-template assisted method. The resulting nanoparticles were subjected to annealing at a temperature of 500ºC for duration of 2 hours. Comprehensive investigations of the nanoparticles such as structural, morphological and optical properties were conducted using a variety of scientific techniques including Powder X-ray diffraction, scanning electron microscopy, UV-diffuse reflectance spectroscopy and Fourier transform Infrared spectroscopy. The findings indicate that N doped TiO2 (N@TiO2) demonstrates superior antibacterial properties compared to bare TiO2, exhibiting a larger inhibition zone for Gram positive microorganisms. Importantly, the controlled synthesis method and the utilization of natural biotemplates offer a sustainable and environmentally friendly strategy for the development of antimicrobial nanomaterials, thereby opening up new avenues for research and innovation within the realm of nanotechnology. The recently formulated N@TiO2 compound has demonstrated impressive antibacterial abilities, particularly targeting S. aureus. In the upcoming days, N doped TiO2 has the potential to be utilized as a substitute therapy or in conjunction with other substances to enhance the effectiveness of treating gram positive bacterial infections.
