Abstract

Rapid advances in materials science, chemistry, and biology as well as industries (e.g., semiconductor and battery industries) demand the development of technologies for physical manipulation and characterization of nano-scaled structures and materials. Nanomanipulation under electron microscopy imaging, due to its unique capability of high precision and programmability for manipulating individual nano-scaled objects, enables new applications in nanomanufacturing and the development and characterization of new nanomaterials. In this context, we develop nanomanipulation instruments, AFM (atomic force microscope), and micro/nano devices for operation inside scanning electron microscopes (SEM). Our research aims to realize a ‘nanofactory’ capable of automated nanomanipulation and multimodal nano-scaled mechanical, electrical, and thermal measurements. In this presentation, I will introduce our LifeForce nanomanipulation instrument and SEM compatible AFM instrument. Example nanomanipulation and characterization tasks enabled by these instruments will be discussed, including automated nanoprobing, electrical/mechanical characterization of nanowires, graphene oxide and transistors, construction of arrays of nanowire  biosensors, and the extraction of DNA from sub-nuclear structures in a single cell nucleus.

 

Biography

Yu Sun is a Professor in the Department of Mechanical and Industrial Engineering, with joint appointments in the Institute of Biomaterials and Biomedical Engineering and the Department of Electrical and Computer Engineering at the University of Toronto. He obtained his Ph.D. in mechanical engineering from the University of Minnesota in 2003 and did his postdoctoral research at ETH-Zürich. He is presently a McLean Senior Faculty Fellow at the University of Toronto and the Canada Research Chair in Micro and Nano Engineering Systems. In 2012-2013, he directed the University of Toronto Nanofabrication Center. Sun has served and serves on the editorial boards of several IEEE Transactions, J. Micromechanics Microengineering, Scientific Reports, and Microsystems & Nanoengineering. Among the awards he received were the McLean Award, the First Prize in Technical Achievement of ASRM (American Society for Reproductive Medicine), and an NSERC E.W.R. Steacie Memorial Fellowship. He was elected Fellow of ASME (American Society of Mechanical Engineers), IEEE (Institute of Electrical and Electronics Engineers), and CAE (Canadian Academy of Engineering) for his work on micro-nano devices and robotic systems.
