Tracking a Drug's Effects on Influenza A (IMAGE) Iowa State University Caption Mei Hong, Iowa State's John D. Corbett Professor in Chemistry, and Sarah Cady, a graduate student in chemistry, are using solid-state nuclear magnetic resonance spectroscopy to study how an anti-virus drug affects influenza A. The technique uses the equipment in front of and behind the researchers. It is similar to the magnetic resonance imaging technology that takes pictures of soft tissues in the body.
