Micro/nanofluidic chips have found increasing applications in the analysis of chemical and biological samples over the past two decades. Electrokinetics has become the method of choice in these micro/nano-chips for transporting, manipulating and sensing ions, (bio)molecules, fluids and (bio)particles, etc., due to the high maneuverability, scalability, sensitivity, and integrability. The involved phenomena, which cover electroosmosis, electrophoresis, dielectrophoresis, electrohydrodynamics, electrothermal flow, diffusioosmosis, diffusiophoresis, streaming potential, current, etc., arise from either the inherent or the induced surface charge on the solid-liquid interface under DC and/or AC electric fields. To review the state-of-the-art of micro/nanochip electrokinetics, we welcome, in this Special Issue of Micromachines, all original research or review articles on the fundamentals and applications of the variety of electrokinetic phenomena in both microfluidic and nanofluidic devices.
Qian, Shizhi
Shizhi Qian received his B.S. and first Ph.D. from Huazhong University of Science and Technology, China in 1994 and 1998, respectively. He worked afterwards as a senior engineer in industry for two years. From February 2001 to August 2002 he worked as a Postdoctoral Researcher in Mechanical Engineering and Applied Mechanics (MEAM), University of Pennsylvania (PENN). From September 2002 to December 2004, he pursued another Ph.D in MEAM at PENN. He was then promoted to Research Associate, and worked at PENN until he became Assistant Professor in the Department of Mechanical Engineering at the University of Nevada Las Vegas (UNLV) in August 2005. He joined the Department of Aerospace Engineering at the Old Dominion University as an Assistant Professor in July 2008 and was promoted to tenured associate professor in July 2011. He was a WCU (World Class University) Fellow in Korea during the period from 2009 to 2014. Since 2002, he has published 150+ peer-reviewed SCI journal articles.
Xuan, Xiangchun
Dr. Xuan is currently an Associate Professor of Mechanical Engineering at Clemson University. He received his PhD degree from the Department of Mechanical and Industrial Engineering at the University of Toronto in 2006 and Bachelor of Engineering degree from the University of Science and Technology of China in 1995. Dr. Xuan was a recipient of the NSF CAREER award in 2012. His research interests cover micro/nanofluidics fundamentals and lab-on-a-chip applications with particular focus on electrofluidics, magnetofluidics and elastofluidics. He has published over 100 articles in leading international journals.
