Nano@Tech welcomes Dr. Zhao, a professor in the Department of Physics and Astronomy at the University of Georgia, on "Catalytic Nanomotors: Challenges and Opportunities."

If you planning to attend, please RSVP by Monday, January 25, 2010.

Abstract:
The fabrication of integrated nanomachinary systems can enable break-through applications in nanoelectronics, photonics, bioengineering, and drug delivery or disease treatment. Naturally occurring nanomotors are biological motor proteins powered by catalytic reactions, which converts the chemical energy into mechanical energy directly. It has been demonstrated recently that using a simple catalytic reaction and an asymmetric bimetallic nanorod, one can produce catalytic nanomotors that mimic the autonomous motions of bionanomotors. Yet, the construction of artificial nanomachines remains a major contemporary challenge due to the lack of a flexible fabrication technique that can design the desired dynamic components.

In this talk, I will discuss our current nanomotor research based on a fabrication method called dynamic shadowing growth technique, and will show some nanomotor components, systems, and their motion behaviors.
