There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

"Smart Bio-nanocomposites for Implantable Materials"

ABSTRACT
Stimuli-responsive nanocomposite materials which change their mechanical properties in response to external stimuli have attracted significant interest for using in broad spectrum applications. The incorporation of high-stiffness, high-surface-area nanofibers with switchable interactions into a polymer matrix has rapidly emerged as a versatile design strategy to create nanocomposites properties that react to a variety of stimuli. We will present our experimental research focused on the design, synthesis and possible applications of materials that change their mechanical properties when implanted in the body. Moreover, we will show biocompatible sensing mechanisms that can be coupled to a range of implantable materials. Ranging from optical fibers to cortical electrodes, we will show several mechanisms that allow long term implantation and sensing within the body.
BIOGRAPHY
E. Johan Foster is an Associate Professor and the Digges Faculty Fellow in Materials Science and Engineering at Virginia Tech. Johan’s expertise are in the design, synthesis, processing and investigation of functional nanocomposites, biomaterials, supramolecular materials and polymers. His research group focuses on the chemistry and engineering of functional bio(nano)materials, imbibing materials with ‘smart’ functionality, often utilizing cellulose nanocrystals (CNCs) as a filler. Johan has many national and international collaborators, from countries as far reaching as Australia, Ghana, France and Switzerland. His research program is supported through federal, industrial and state research grants.
The Petit Institute has revolutionized the term "interdisciplinary research," and has become internationally recognized for its ability to tackle complex research problems by bringing engineering and scientists together. It has grown to include 190 faculty members from a wide variety of disciplines, which has played a vital role in building its dynamic culture.
The Renewable Bioproducts Institute at Georgia Tech builds on nearly a century of lignocellulosics research to advance business opportunities based on renewable resources for today and tomorrow.
