Ecoseed: Scientists at the University of Missouri used cinnamon to replace almost all the toxic chemicals needed for making gold nanoparticles. They mixed gold salts with cinnamon and stirred the mixture in water. Kattesh Katti, professor of radiology and physics in the School of Medicine and the College of Arts and Science, said the process is environmentally friendly because it uses no electricity and utilizes no other toxic chemicals. Gold nanoparticles are used in electronics and healthcare. Katti uses his for cancer treatment, which was the focus of his study published in Pharmaceutical Research.
