Green sonochemistry assisted synthesis of hollow magnetic and photoluminescent MgFe 2 O 4 –carbon dot nanocomposite as a sensor for toxic Ni( ii ), Cd( ii ) and Hg( ii ) ions and bacteria

The purpose of this study is synthesis of magnetic and photoluminescence nanoparticles at the same time for finding of bacteria that could be fatal and its detection are crucial for some illness prohibition.
