“…Higher photocatalytic efficiency of TiO 2 nanoparticles can be used for purification and remediation of environment and also employed for the removal of dye pollutants and biowaste organic compounds. TiO 2 releases free radicals such as OH, O 2 , HO À 2 , and H 2 O 2 on exposure of ultraviolet irradiation [4,5]. This potent *Corresponding author.…”

In the present work, we have reported a sustainable and effective method for the degradation of a textile dye Reactive Red 31 (RR31) using synthesized titanium nanoparticles. Titanium dioxide nanoparticles were synthesized using a noxious weed, Parthenium hysterophorus, as reducing and capping agent for the first time. The synthesized nanoparticles were characterized and confirmed as TiO 2 nanoparticles by using X-ray diffraction spectroscopy, Fourier transformation infrared spectroscopy, and scanning electron microscopy analysis. A glass reactor was designed and developed for the degradation of dye under solar radiations. Photocatalytic degradation of Reactive Red 31 was carried out at different concentrations using synthesized nanoparticles. UV-vis spectroscopy, total organic carbon, and total inorganic carbon analysis were carried out for the determination of dye degradation. The results reveal that biogenic TiO 2 nanomaterial acts as a good photocatalyst for the degradation of textile dye Reactive Red 31.

“…The minimum inhibitory concentration value was 40 µg/mL for E. coli treated with fungus-mediated synthesized TiO2 nanoparticles [104]. The antibacterial activity of biogenically synthesized TiO2 nanoparticles (28-54 nm) that were obtained from the bacteria Aeromonas hydrophila was reported for S. aureus and S. pyogenes [105]. Therefore, biogenically synthesized TiO2 nanoparticles can have contradictory antibacterial effects, depending on the biological reducing and capping agent that is employed during the biogenic synthesis processes.…”

This review discusses recent advances in the synthesis, characterization and toxicity of metal oxide nanoparticles obtained mainly through biogenic (green) processes. The in vitro and in vivo toxicities of these oxides are discussed including a consideration of the factors important for safe use of these nanomaterials. The toxicities of different metal oxide nanoparticles are compared. The importance of biogenic synthesized metal oxide nanoparticles has been increasing in recent years; however, more studies aimed at better characterizing the potent toxicity of these nanoparticles are still necessary for nanosafely considerations and environmental perspectives. In this context, this review aims to inspire new research in the design of green approaches to obtain metal oxide nanoparticles for biomedical and technological applications and to highlight the critical need to fully investigate the nanotoxicity of these particles.

“…The photocatalysis process of nano-TiO 2 includes chemical steps that produce highly reactive oxygen species, such as hydroxyl radical, hydrogen peroxide, and superoxide ions. The bactericidal effect of nano-TiO 2 is generally attributed to the decomposition of bacterial outer membranes by reactive oxygen species [29,30]. Superoxide ions cannot penetrate into the cell membrane of aspergillus due to their negative charge, but they are relatively longer lived.…”
