“…The chemical approaches involve coating (dip, spin, and spray), co-precipitation, ultrasonication wet impregnation, photoreduction, hydrothermal and solvothermal processing, electrochemical anodization and electrospinning, and sol-gel (Orlianges et al, 2012;Zhu et al, 2017;Johari et al, 2019). Latha and Lalithamba (2018) synthesized spherical-shaped anatase-phased TiO 2 NPs by using a hydrothermal method, which was calcinated at 400 • C. Vajedi and Dehghani (2016) synthesized ∼12 nm TiO 2 NPs by using a solvothermal method, which was capped by using diethyl oxalate (Vajedi and Dehghani, 2016). Buraso et al (2018) synthesized TiO 2 NPs of size 11.3 to 27.4 nm under varying calcination temperatures of 400-700 • C. The precursor used here was titanium (IV) isopropoxide, and the synthesis method was a simple precipitation method.…”

Nanotechnology (NT) and nanoparticles (NPs) have left a huge impact on every field of science today, but they have shown tremendous importance in the fields of cosmetics and environmental cleanup. NPs with photocatalytic effects have shown positive responses in wastewater treatment, cosmetics, and the biomedical field. The chemically synthesized TiO2 nanoparticles (TiO2 NPs) utilize hazardous chemicals to obtain the desired-shaped TiO2. So, microbial-based synthesis of TiO2 NPs has gained popularity due to its eco-friendly nature, biocompatibility, etc. Being NPs, TiO2 NPs have a high surface area-to-volume ratio in addition to their photocatalytic degradation nature. In the present review, the authors have emphasized the microbial (algae, bacterial, fungi, and virus-mediated) synthesis of TiO2 NPs. Furthermore, authors have exhibited the importance of TiO2 NPs in the food sector, automobile, aerospace, medical, and environmental cleanup.

“…Among chemical approaches, the most popular ones are sol-gel ( Ullattil and Periyat, 2017 ), precipitation ( Buraso et al, 2018 ), ultrasonication, hydrothermal ( Shahat et al, 2021 ), microwave-assisted synthesis ( Kubiak et al, 2020 ), and chemical vapor deposition (CVD) ( Wahyudiono et al, 2022 ). Among physical routes, the most preferred techniques are electron beam deposition ( Latha and Lalithamba, 2018 ), magnetron sputtering ( Daughtry et al, 2021 ), spray pyrolysis ( Aboulouard et al, 2022 ), ball milling ( Carneiro et al, 2014 ), etc. Though some of these approaches are very rapid and efficient but have several demerits i.e., the requirement of expensive synthesis techniques in the physical approaches.…”

Over the last decade there has been a huge increase in the green synthesis of nanoparticles. Moreover, there is a continuous increase in harnessing the potential of microorganisms for the development of efficient and biocompatible nanoparticles around the globe. In the present research work, investigators have synthesized TiO2 NPs by harnessing the potential of Bacillus subtilis MTCC 8322 (Gram-positive) bacteria. The formation and confirmation of the TiO2 NPs synthesized by bacteria were carried out by using UV-Vis spectroscopy, Fourier transforms infrared (FT-IR), X-ray diffraction (XRD), scanning electron microscope (SEM), and energy dispersive X-ray spectroscopy (EDX/EDS). The size of the synthesized TiO2 NPs was 80–120 nm which was spherical to irregular in shape as revealed by SEM. FTIR showed the characteristic bands of Ti-O in the range of 400–550 cm−1 and 924 cm−1 while the band at 2930 cm−1 confirmed the association of bacterial biomolecules with the synthesized TiO2 NPs. XRD showed two major peaks; 27.5° (rutile phase) and 45.6° (anatase phase) for the synthesized TiO2 NPs. Finally, the potential of the synthesized TiO2 NPs was assessed as an antibacterial agent and photocatalyst. The remediation of Methylene blue (MB) and Orange G (OG) dyes was carried out under UV- light and visible light for a contact time of 150–240 min respectively. The removal efficiency for 100 ppm MB dye was 25.75% and for OG dye was 72.24% under UV light, while in visible light, the maximum removal percentage for MB and OG dye was 98.85% and 80.43% respectively at 90 min. Moreover, a kinetic study and adsorption isotherm study were carried out for the removal of both dyes, where the pseudo-first-order for MB dye is 263.269 and 475554.176 mg/g for OG dye. The pseudo-second-order kinetics for MB and OG dye were 188.679 and 1666.667 mg/g respectively. In addition to this, the antibacterial activity of TiO2 NPs was assessed against Bacillus subtilis MTCC 8322 (Gram-positive) and Escherichia coli MTCC 8933 (Gram-negative) where the maximum zone of inhibition in Bacillus subtilis MTCC 8322 was about 12 mm, and for E. coli 16 mm.
