Cinnamon Could Replace Harsh Chemicals To Produce Gold Nanoparticles, Researchers Say
Cinnamon Nanotubes? Cinnamon can be used as a replacement for toxic chemicals in the production of gold nanoparticles, scientists say. Wikimedia Commons A humble spice found in nearly every kitchen could yield a safer, simpler way to produce gold nanoparticles, according to a new study. Researchers say the cinnamon-infused particles can even be used to fight cancer. Gold nanoparticles are heralded for their potential to detect tumors, search for oil, light the streets and cure diseases, but their production requires dangerous toxic chemicals. There are several ways to produce gold particles, but most involve dissolving chloroauric acid, also called gold salts, in liquid and adding chemicals to precipitate gold atoms. Common mixtures include sodium citrates, sodium borohydride (also used to bleach wood pulp) and ammonium compounds, all of which can be toxic to humans and the environment. Hoping to promote green nanotechnology, researchers at the University of Missouri mixed gold salts with...
