Phytofabrication of TiO2 nanoparticles and their antibacterial efficacy: a study using Cucumis sativus and Raphanus sativus

Green synthesis has attained a great importance in the field of science due to its enormous advantages over conventional methods. The synthesis of metal nanoparticles from plants is a convenient and ecofriendly process with its applications in various fields like drug delivery, environmental remediation and agriculture sector. The present study describes the synthesis of titanium nanoparticles by Cucumis sativus, and Raphanus sativus using simple method. The nanoparticles synthesized using plant extracts were calcinated at 400 o C to obtain the dried nanoparticles and characterized through various characterization techniques like X-ray diffraction (XRD), Fourier-transformed infrared spectroscopy (FTIR), Energy dispersive X-ray spectroscopy (EDX), and Scanning electron microscope (SEM). The characteristic peak for the synthesis of TiO2 nanoparticles was appeared in FTIR. The phytochemicals present in the plant extract act as capping as well as reducing agents and are responsible for the synthesis of metallic nanoparticles. The antibacterial activity of green synthesized nanoparticles was assessed against various bacterial strains. The good antibacterial properties of titanium nanoparticles suggest their useful applications in the field of medicine.
