Wang, Wei is a professor in the Department of Microelectronics, School of EECS, and has served as the Deputy Director of Institute of Microelectronics since 2016, deputy director of the National Key Lab of Micro/Nano Fabrication Technology since 2012, and the director of the MEMS center since 2016. He obtained his B.Eng. from the University of Shanghai Science and Technology in 1999, and Ph.D. from Tsinghua University in 2005 respectively. He has worked as a visiting professor in UC Davis since 2007.08-2008.03 with Prof. Tingrui Pan and in Caltech since 2014.08-2015.07 with Prof. Yu-Chong Tai. His research interests include micro/nanofluidics, polymer micro/nanofabrication and clinical micro/nanodevices.
Dr. Wang has published more than 70 research papers, and most of them are published in top-tier journals and conferences, such as Lab on a Chip, Applied Physics Letters, Biomicrofluidis, IEEE MEMS, Transducers, and MicroTAS. He has served in the Technical Program Committee of various international conferences including IEEE MEMS (2015, 2016), Transducers (2017), IEEE NEMS (2012, 2017), etc., and as Co-Chair of Advances in Microfluidics and Nanofluidics (2015). He is serving as a guest editor of Micromachines now. Dr. Wang was selected as Emerging Investigator by Lab on a Chip in 2010 (The first emerging investigator selection by the journal), the only awardee in the Great China region, including Taiwan, Hongkong and Macau.
Dr. Wang has more than ten research projects including NSFC, 973 programs, etc. His research achievements are summarized as follows:
1) Parylene based micro/nanofabrication techniques: Parylene is the widest used polymer material in the micro/nanoelectromechanical systems (M/NEMS). Dr. Wand has developed a highly reliable and controllable ultra-thin Parylene deposition approach for the deposition with thickness as low as 1 nm. He advanced an annealing process for autofluorescence enhancement of Parylene C and implemented this technique for various fluorescence marking applications, including addressable neuronal electrophysiology. He optimized the Parylene C caulked PDMS process to enabling a hybrid material (pcPDMS) with a low small molecule permeability.
2) Nanofluidic crystal: With various promising applications demonstrated, nanofluidics has been of broad research interest in the past decade. Dr. Wang innovatively developed a nanofabrication-free, high-throughput, yet precisely controllable and modellable nanofluidics in a close-packed nanoparticle array, i.e. the nanofluidic crystal. He implemented nanofluidic crystal in various applications, including ultra-high-current ionic diodes, ultra-high-power energy harvesters, and ultrasensitive biosensors.
3) Ultra-high throughput liquid biopsy: Liquid biopsy is the sampling and analysis of non-solid biological tissue, such as primarily blood or other body fluid or clinical fluid. Dr. Wand developed an ultra-high throughput liquid biopsy based on a Parylene C micropore array with an ultra-high porosity. The throughput can go up to 130 mL/min for a PBS solution and 25 mL/min for the whole blood sample, while the reported data in the literature only showed up a 2 mL/min at most. The technique will find wide applications in various cancer diagnoses.
