“The original procedure Katti used to create the gold nanoparticles required the use of hazardous chemicals, such as sodium borohydride and hydrazine. Katti resolved this problem by substituting plants. Plants like cinnamon and tea leaves, which are staples in the human diet, contain electron-rich antioxidants necessary for converting the base of the nanoparticles, gold compounds, into the gold nanoparticles. The antioxidants reduce the gold compounds down to the nanoparticles through chemical reduction and then stabilize them to prevent them from binding together”….Article by Taylor Malottki
