Nanowire field-effect transistors (NWFETs) represent diverse and powerful nanostructures for achieving nanoscale bioelectronic interfaces with cells and tissue. NWFETs exhibit exquisite sensitivity in chemical and biological detection and can form strongly coupled electrical interfaces with cellular components. My talk will focus on several biomimetic design considerations towards breaking down the boundary between nonliving and living systems across multiple length scales. I will describe how we experimentally apply these designs in the nanoelectronic systems for building electrically active, minimally invasive interfaces with single cells and synthetic tissue. Specifically, I will discuss a new synthetic approach and novel fabrication method to realize the first semiconductor transistor bioprobe for intracellular measurements from a truly three-dimensional nanoscale device. In addition, recent progress on nanoelectronically addressable synthetic tissue will also be discussed. Finally, I will describe the prospects in future fundamental studies and applications in the life sciences.

Biography of Bozhi Tian:
Dr. Tian received the B.S. and M.S. degrees in chemistry from Fudan University, Shanghai, China, and the A. M. and Ph. D. degrees in physical chemistry from Harvard University in 2010, Cambridge, MA. His Ph.D. research with Professor Charles Lieber include new nanowire materials synthesis, the fundamental study of high performance nanowire photovoltaics and the application of novel nanowire devices in cells and tissue. He worked with Professors Robert Langer and Daniel Kohane as a postdoctoral scholar in tissue engineering and regenerative medicine. He is now an assistant professor at the University of Chicago, working on semiconductor based biophysics. Dr. Tian’s accolades include 2013 NSF CAREER award, 2013 Searle Scholar award, 2012 TR35 honoree, 2011 IUPAC Prize for Young Chemists award, the third Place in 2010 National Collegiate Inventors Competition, 2009 American Chemical Society Division of Inorganic Chemistry’s Young Investigator Award and 2008 Graduate Student Award from the Materials Research Society.
