Abstract: In this talk, Dr.Fan will discuss innovative concepts and approaches for robotizing functional nanoentities into highly controllable nanomotors for single-cell drug delivery, bioanalysis, and tunable biochemical release. Arrays of designed nanoparticles can be precisely transported along arbitrary trajectories, assembled, and actuated as various nanoelectromechanical (NEMS) devices (or nanomotors) by the electric tweezers — their recent invention. The nanomotors can deliver biosignals to a single live cell amidst many for signal transduction. Here, the rotary nanomotors, with nanowires and nanomagnets as building blocks, are the smallest (all dimensions < 1 µm), fastest (18,000 rpm), and most durable rotary NEMS (continuously operate for 15 hours over 240,000 cycles). The innovations reported in this research, from concept, design, actuation, to application could be inspiring for NEMS, nanomedicine, microfluidics, and lab-on-a-chip architectures.
Biography: Dr. Donglei (Emma) Fan is an Assistant Professor in the Department of Mechanical Engineering of the University of Texas at Austin since 2010. She received National Science Foundation CAREER award in 2012. She was one of 60 US and Europe young engineers, invited to attend the National Academy of Engineering (NAE) 2013 EU-US Frontier of Engineering Symposium in France. She was honored as a Recognized Mentor by the Siemens Foundation in 2012, a finalist of the Beckman Young Investigator Award (24 finalists nationwide). Prof. Fan's work has spurred a series of publications on leading journals including Nature Nanotechnology, Nature Communications, the Proceedings of National Academy of Sciences, Nano Today, Physical Review Letters, Advanced Materials, Advanced Functional Materials, ACS Nano, Applied Physics Letters, as well as a few pending patents.
