This research focused on studying the use of leaf extract to create titanium dioxide (TiO2) nanoparticles in an eco-sustainable manner. The nanoparticles were thoroughly examined using techniques and their ability to combat E. coli bacteria was assessed. In the synthesis process the pomegranate leaf extract acted as both a reducing agent and a stabilizer. To confirm the formation of TiO2 nanoparticles UV visible spectroscopy was employed to detect absorption peaks associated with these particles. Fourier Transform Infrared (FTIR) spectroscopy provided insights, into the groups in the extract that played a role in reducing and coating the nanoparticles. X ray diffraction (XRD) analysis revealed that the TiO2 nanoparticles possessed a crystalline structure while Atomic Force Microscopy (AFM) allowed for examination of their nanoscale surface characteristics and topography. Subsequently tests were conducted to evaluate how effectively the synthesized TiO2 nanoparticles could inhibit E. coli Bacteria growth showing promising effects that increased with higher concentrations. These findings highlight the potential of using TiO2 nanoparticles created with leaf extract as a solution for combating bacterial infections. Furthermore, this research adds to the progress of creating biocompatible nanomaterials using natural extracts. It opens opportunities for their application in domains, like medicine, environmental restoration, and nanotechnology.
