Prof. Joseph Wang
Department of Nanoengineering, UC San Diego
May 7, 2010 | 11:00 to 12:00 | 105 Stanley Hall
Host: Luke Lee
The remarkable performance of biomotors is inspiring scientists to create synthetic nanomachines that mimic the function of these amazing natural systems. This presentation will discuss the challenges and opportunities facing the design and operation of artificial nanomotors. Particular attention will be given to catalytic nanowire and microtube motors propelled by the electrocatalytic decomposition of a chemical fuel. While artificial nanomotors still pale compared to natural biomotors, recent advances indicate significant improvements in the velocity, power, motion control, cargo-towing force, scope and versatility of such catalytic nanomotors. The greatly improved capabilities of chemically-powered artificial nanomotors could pave the way to exciting and important applications and to sophisticated nanoscale devices performing complex tasks.
