| Popis: | Bio-synthesis of TiO2 nanoparticles was accomplished with Ocimum americanum L leaf extracts. The morphology, optical and functional properties of synthesized TiO2 nanoparticles were characterized by XRD, UV–Vis spectroscopy, FT-IR, and FE-SEM with EDAX respectively. The aqueous extracts of these nanoparticles were evaluated for its antimicrobial activities against Bacillus cereus, Clostridium perfringens, Salmonella paratyphi, Klebseilla pnemoniae, Candida albicans and Aspergillus niger using an agar well method. The antiproliferative activity was analyzed by MTT assay. Photocatalytic analysis against methylene blue dye was investigated. The biosynthesized TiO2 nanoparticles was analyzed by SEM with an average size of the particle was 25 nm. The synthesized TiO2 nanoparticles were exhibited excellent antimicrobial and antiproliferation activities against selected pathogens and human skin cancer cell line (431) respectively and expression of admirable photocatalytic activity with reduction of 91.1%. Based on the above studies, it is concluded that these nanoparticles are eco-friendly, inexpensive and pollution free material which can be applied for multifaceted environmental applications. |
