“The Small Looms Large: Applying Millimeter-Scale Chips to Scientific Research”



Rapid downscaling of semiconductor technology has enabled the possibility of integrating billions of transistors onto a single silicon chip, allowing ultra-fast signal processing at low power and cost. While their transformative effects on computers and mobile devices have been witnessed, these semiconductor chips are also potentially powerful instruments for emerging scientific application, especially for biomolecular detection. In this talk, several point-of-care diagnostic platforms based on customized semiconductor from the SKL-AMSV will be presented. By utilizing nuclear magnetic resonance based sensing mechanism, these handheld platforms (< 2 kg) enable low-cost, rapid, and quantitative DNA and protein detections with tiny semiconductor chips (e.g., <0.08 cm2). Further, with innovative engineering techniques such as magnetic field stabilization and integration of sample manipulation network, the proposed platforms show promise as robust and portable diagnostic devices for a wide variety of biological analyses and screening applications.



Ka Meng Lei received the B.Sc. degree in electrical and electronics engineering, and graduated from Honours College from University of Macau in 2012. He received his Ph.D. degree in electrical and computer engineering from the State-Key Laboratory of Analog and Mixed-Signal VLSI and Faculty of Science and Technology, University of Macau in Nov. 2016.

Currently he serves as a lecturer under UM Macao Fellow program at the University of Macau. His research interests include sensors and analog front-end interfaces, analog circuit techniques for micro-NMR, and system planning, integration, and optimization for biomedical devices. His research achievements have been published and presented in prestigious peer-reviewed journals and conferences, including IEEE Journal of Solid-State Circuits, Lab on a chip, and IEEE International Solid-State Circuits Conference. He is the recipient of several regional and international awards, including the IEEE Solid-State Circuit Society Pre-doctoral Achievement Award 2017 and the FDCT Macao Science and Technology Award for Postgraduates 2016 (Ph.D. level).
