Handheld CMOS NMR Biosensor
This talk will showcase how silicon RF chips can be used not only for wireless RF applications, but also for biomolecular sensing aimed at low-cost disease screening. The main function of the RF chip is to manipulate and monitor the dynamics of protons in water via nuclear magnetic resonance (NMR). Target biological objects such as cancer marker proteins alter the proton dynamics, which is the basis for the biosensing. The high sensitivity of the RF chip made possible the construction of an entire NMR system around the RF chip in a 100-g platform, which is 1200 times lighter, yet 150 times more spin-mass sensitive than a state-of-the-art commercial benchtop NMR system. The system can become a useful addition in pursuing disease detection in a low-cost, hand-held platform.
Nan Sun is Associate Professor in the Department of Electrical and Computer Engineering at the University of Texas at Austin. He received the B.S. degree from Tsinghua University, Beijing, China in 2006, where he ranked top in Department of Electronic Engineering. He received the Ph.D. degree from the School of Engineering and Applied Sciences at Harvard University in 2010.
Dr. Sun holds the AMD Endowed Development Chair position at UT Austin. He received NSF Career Award in 2013, and Jack Kilby Research Award from UT Austin in 2015. He also received Samsung Fellowship, Hewlett Packard Fellowship, and Analog Devices Outstanding Student Designer Award in 2003, 2006, and 2007, respectively. He won Harvard Teaching Award in three consecutive years: 2008, 2009, and 2010. He serves in the TPC of Asian Solid-State Circuit Conference. He is an Associate Editor for IEEE Transactions on Circuits and Systems – I: Regular Papers.
His research interests include: 1) analog, mixed-signal, and RF integrated circuits; 2) miniature spin resonance systems; 3) magnetic sensors and image sensors; 4) developing micro- and nano-scale solid-state platforms (silicon ICs and beyond) to analyze biological systems for biotechnology and medicine.
