Nano/Microscale Machines: Recent Designs and Applications

McDonnell Douglas Engineering Auditorium

Prof. Joseph Wang

Department of Nanoengineering

  University of California, San Diego


The remarkable performance of biomotors is inspiring scientists to create synthetic Nanoscale machines 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 and demonstrate their prospects for diverse biomedical applications. Particular attention will be given to recent advances in catalytic microtube motors propelled by the catalytic decomposition of a chemical fuel, as well as to fuel-free (magnetically or ultrasound-driven) nanomotors. These developments indicate significant improvements in the velocity, power, motion control, cargo-towing force, scope and versatility of synthetic nanomotors. The greatly improved capabilities of artificial nanomotors pave the way to exciting and important applications ranging from drug delivery, target isolation, surface patterning or environmental remediation.
