Abstract
In the present study, confirmation of Spirulina platensis-mediated TiO2NPs formation was indicated by a noticeable shift in hue from white to light yellow. TEM analysis revealed the presence of irregularly distributed nanoparticles with sizes between 50 and 60 nm, while TEM analysis further disclosed a hexagonal structure. EDAX analysis identified elemental composition, with titanium peaks appearing at 4.5 to 5 keV, carbon peaks at 0.5 keV, oxygen peaks at 0.4 to 1.0 keV, silica peaks at 1.7 to 2.0 keV, zinc peaks at 8.0 keV, copper peaks at 7 keV, potassium peaks at 4 keV, phosphorus peaks at 3 keV, and iron peaks at 6 keV. These comprehensive findings confirm the successful synthesis of well-defined Spirulina platensis-mediated TiO2 nanoparticles and provide valuable insights into their structural and elemental characteristics.
Keywords: Spirulina, TiO2 NPs and TEM with EDAX analysis
