New Nanoparticles for Biomedical Testing

4/6/2011

Dr. Jessica Winter, Assistant Professor, Chemical and Biomolecular Engineering and Biomedical Engineering, Ohio State University

Engineers at Ohio State University say they have invented a new kind of nanoparticle that shines in different colors to tag molecules in biomedical tests. The plastic nanoparticles are stuffed with quantum dots that glow brightly in red, yellow, or green, so researchers can track molecules under a microscope. This is the first time anyone has created fluorescent nanoparticles that can change colors continuously, according to the scientists.

During this week’s podcast, research team member Dr. Jessica Winter provides additional details on the new nanoparticle. She also discusses the advantages of using quantum dots instead of fluorescent materials when tagging molecules. In addition, Dr. Winter talks about some of the novel life science and medical applications for the nanoparticle and explains what types of research projects are under way to further develop the technology.

Jessica Winter is the H.C. “Slip” Slider assistant professor in the departments of Chemical and Biomolecular Engineering (ChE) and Biomedical Engineering (BME) at the Ohio State University. She received her Ph.D. in Chemical Engineering from the University of Texas at Austin in 2004 and completed a postdoctoral fellowship at the Center for Innovative Visual Rehabilitation, a collaborative effort between the Boston VA Hospital, Harvard Medical School, and the Massachusetts Institute of Technology, in 2006. Her current research interests include the development of biomimetic, polymeric materials for the brain, and the development of multifunctional nanoparticles for biological manipulation and imaging.
