Atomically-thin materials such as single-walled carbon nanotubes (SWCNT) and graphene are prone to chemical attack because all of the constituent atoms are exposed. In this talk, I will discuss our progress on the synthetic creation of a tube-in-a-tube (Tube^2) semiconductor and their implications on biochemical sensing. A Tube^2 is equivalent to a pristine SWCNT nested within a chemically tailored, impermeable, and atomically-thick functional shell. Compared with SWCNTs and graphene, electrical sensors created using Tube^2 can be readily tailored with robust covalent chemistries to enable chemical selectivity while maintaining exceptional SWCNT-like sensitivity. Recent progress from our lab as well as some of the challenges and opportunities in this area will be discussed.


Dr. YuHuang Wang is a Professor of Chemistry at the University of Maryland, College Park. His research group focuses on developing innovative chemistry, materials, and instrumentation to address fundamental problems in energy, biomedicine and quantum electronics. He is the author of more than 90 manuscripts and 20 patents and applications in the areas of carbon nanotechnology, molecular printing, and energy technology.Dr. Wang received a B.S. degree in chemistry from Xiamen University, China. He did his Ph.D. studies with Richard E. Smalley at Rice University and postdoctoral research with Chad A. Mirkin at Northwestern University prior to joining the Maryland faculty in fall 2008. He has been a full professor there since 2017.
