Abstract

Recent advances in Nano science and nanotechnology changed the pattern of how we diagnose, treat, and prevent various diseases in all aspects of human life. Also, they were enormously used in removal of synthetic dyes present in textile dye effluent. TiO₂ nanoparticles (TiO₂NPs) are one of the most life-sustaining and captivating nanoparticle among several metallic nanoparticles that are involved in biomedical applications as well as in bioremediation. TiO₂NPs are crucial to nanotechnology and Nano science, especially in bioremediation and Nano medicine. In this study, we used a biological approach to synthesize TiO₂NPs. SEM-EDX and XRD were used to characterize the synthesized nanoparticles. More significantly, the current work concentrated on the many bio-applications of TiO₂NPs, such as their antibacterial properties and their ability to bio-mediate synthetic dyes. By using a conventional technique, the antimicrobial activity of TiO₂ nanoparticles was assessed. It was discovered that TiO₂ nanoparticles exhibited notable antibacterial activity against S. aureus, E. coli, Pseudomonas species, and Klebsiella. TiO₂ NPs can be used to break down azo dyes, like Acid Red 3BN and Acid Yellow, which are utilized in many textile sectors and are highly harmful to the environment. TiO₂ nanoparticles were extracellular synthesized using Aspergillus Niger which was isolated from the industrial area and Curvularia spp. found in area near textile industry the formation of nanoparticles was observed after 144hrs of incubation. Decolorization was observed by color changes UV-visible spectroscopy, FTIR, X-Ray diffraction XRD and SEM (EDX) From the SEM images, it is concluded that the TiO₂ NPs are crystalline in nature. In FTIR of TiO₂ NPs the peak at 1550 cm-1 was observed which corresponds to the TiO₂ vibration present in crystalline structure.
