Abstract
Biosynthesis of metal oxide nanoparticles has attracted much attention in recent years owing to the increasing impact for improving hygienic substances, cost effective approaches, environment friendly solvents and reusable resources. The present study has shown the eco synthesis of TiO2 nanoparticles using the aqueous extract of egg shell waste. UV, XRD, FT-IR, and FE-SEM with EDX methods were implied for TiO2 nanoparticles. The agar well approach was used to investigate the antimicrobial properties of biosynthesized nanoparticles against pathogenic organisms. The cytotoxicity analysis was investigated by MTT assay method and photocatalytic activity was studied using methylene blue, methyl orange and Congo red dye. X-ray diffraction studies showed that the presence of tetragonal structure. The crystallite size of synthesized TiO2 nanoparticles is 27.3 nm. FE-SEM analysis indicates that the average grain size of the prepared sample was found to be in the range of 30–40 nm. Eco synthesis of TiO2 nanoparticles displayed amazing antimicrobial efficacies against human pathogenic organisms and obtained excellent cytotoxicity investigation was performed against Osteosarcoma cell lines (MG-63). Further it was also found that the expression of impressive catalytic efficiency, 91.1 percent decreased in 60 min for methylene blue. From the results, we found that eco synthesized TiO2 nanoparticles has promising utility in multidisciplinary like antimicrobial, anticancer and photocatalytic applications.
