MU scientists go green with gold, distribute environmentally friendly nanoparticles
Date:9/26/2008

COLUMBIA, Mo. -- Gold nanoparticles are everywhere. They are used in cancer treatments, automobile sensors, cell phones, blood sugar monitors and hydrogen gas production. However, until recently, scientists couldn't create the nanoparticles without producing synthetic chemicals that had negative impacts on the environment. A new method, created by a University of Missouri research team, not only eliminates any negative environmental impact, but also has resulted in national and international recognition for the lead scientist. The research was published recently in the journal Small.

"I have always believed that nature is smarter and stronger than humankind," said Kattesh Katti, professor of radiology and physics in MU's School of Medicine and College of Arts and Science, senior research scientist at the MU Research Reactor, and director of the MU Cancer Nanotechnology Platform. "This new procedure to create nanoparticles is wonderfully simple, yet it will help create very complex components. There is so much to learn from energy generation, chemical and photochemical reactions of plants."

Katti, who was recently recognized by rt Image magazine as one of the 25 most influential people in radiology, and his research team have formed Greennano Company, a company that is in the beginning stages of producing environmentally friendly gold nanoparticles. The company will focus on the development, commercialization and worldwide supply of gold nanoparticles for medical and technological applications. Katti believes that because of this new process to produce the nanoparticles, researchers are developing other ways to use them.

The MU research team, which was led by Katti, Raghuraman Kannan and Kavita Katti, found that by submersing gold salts in water and then adding soybeans, gold nanoparticles were generated. The water pulls a phytochemical out of the soybean that is effective in reducing the gold to nanoparticles. A second p
