Abstract

Rapidadvances in materials science, chemistry, and biology as well as industries(e.g., semiconductor and battery industries) demand the development oftechnologies for physical manipulation and characterization of nano-scaledstructures and materials. Nanomanipulation under electron microscopy imaging,due to its unique capability of high precision and programmability formanipulating individual nano-scaled objects, enables new applications innanomanufacturing and the development and characterization of newnanomaterials. In this context, we develop nanomanipulation instruments, AFM(atomic force microscope), and micro/nano devices for operation inside scanningelectron 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 introduceour LifeForce nanomanipulation instrument and SEM compatible AFM instrument.Example nanomanipulation and characterization tasks enabled by theseinstruments will be discussed, including automated nanoprobing,electrical/mechanical characterization of nanowires, graphene oxide andtransistors, construction of arrays of nanowire biosensors, and the extraction of DNA from sub-nuclear structures in asingle cell nucleus.

Biography

YuSun is a Professor in the Department of Mechanical and Industrial Engineering,with joint appointments in the Institute of Biomaterials and BiomedicalEngineering and the Department of Electrical and Computer Engineering at theUniversity of Toronto. He obtained his Ph.D. in mechanical engineering from theUniversity of Minnesota in 2003 and did his postdoctoral research atETH-Zürich. He is presently a McLean Senior Faculty Fellow at the University ofToronto and the Canada Research Chair in Micro and Nano Engineering Systems. In2012-2013, he directed the University of Toronto Nanofabrication Center. Sunhas 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 inTechnical Achievement of ASRM (American Society for Reproductive Medicine), andan NSERC E.W.R. Steacie Memorial Fellowship. He was elected Fellow of ASME(American Society of Mechanical Engineers), IEEE (Institute of Electrical andElectronics Engineers), and CAE (Canadian Academy of Engineering) for his workon micro-nano devices and robotic systems.
