The transfer of engineered nanomaterials out of nanotechnology-enabled food packaging

Dr. Timothy V. Duncan

Polymer nanocomposites (PNCs) are an emerging class of materials in which nanoscale fillers are dispersed within a polymer host. PNCs have attracted considerable interest as next generation food packaging, medical devices, and other consumer product applications. To ensure responsible development and implementation of this technology, there is a need to understand the quantity and form of dispersed nanofillers that may transfer out of PNCs and into nearby environments, including foods, during product lifecycles. Relationships between nanofiller structure/composition, host polymer properties, environmental chemistry, and the fate of nanomaterials dispersed in plastics especially need to be better understood. This talk will present our laboratory’s latest research to study release of engineered nanomaterials from nanotechnology-enabled food packaging. Topics presented include: fabrication and characterization of nanocomposite materials using silver, gold, clay, and quantum dot nanofillers, chemical analysis of food simulants and foods/beverages for transferred nanofillers and their dissolved residuals, and information about mass transport physics within polymers and nanoparticle transformation phenomena in relevant environments.




Timothy V Duncan received his undergraduate degree in chemistry in 2000 fromHaverfordCollege, located just outside of Philadelphia. He attained his Ph.D. in physical/inorganic chemistry in 2006 from the University of Pennsylvania, where he studied electronic materials for medical diagnostic and optoelectronic applications under Professor Michael J. Therien. After graduation, he completed a post-doc at the University of Pennsylvania with Professor So-Jung Park, which focused on single-molecule spectroscopy, novel bio-imaging agents, and color-tunable luminescent polymers. Since 2009 he has been a research scientist and primary investigator at the U.S. Food and Drug Administration’s Division of Food Processing Science and Technology, where he studies the health and environmental safety of nanotechnology-enabled food contact materials and develops nanosensors intended to improve the Agency’s ability to rapidly respond to foodborne disease outbreaks.
