biosynthesis of gold nanoparticles by opuntia ficus-indica extract and processing environmental contamination of eosin dye

Using prickly pear juice and a green chemistry technique, aunps were created for this study. the uv-visible spectrophotometer was used to verify the synthesized aunps. whereas peak position was at 548 nm while in fourier transform infrared (ftir) spectroscopy was less than 500 1/cm, scanning electron microscopy (sem) showing spherical in structure and x-ray diffraction with a size 19.92-133.97 nm, the optical effect of gold nanoparticles were impact in get rid of eosin remain by increasing the optical analysis of pollutants. the hemolysis percentage is < 5% which indicates that these nanoparticles are not toxic.
