Chemistry09/16/2022 01:50 pm In-Person Halsey room 457 Real-time Chemical and Biosensors for Health, Environment, and Energy Applications Xiangqun Zeng, Ph.D. and Distinguished Professor Chemistry Department, Oakland University, Rochester, MI 48309 Abstract In recent years, sensor research has experienced a revolution, promising to have a significant impact on a broad range of applications relating to national security, health care, the environment, energy, food safety, and manufacturing etc. This presentation will discuss some of the key technological developments of chemical and biosensors, particularly, the real-time electrochemical sensor technology that has taken place in the past decades in our laboratory for health, environmental and energy applications. It will include a few topics: (1) general theory of sensors; (2) basic characteristics and applications of sensors; (3) unique sensing elements and interface reactions, particularly, using the combination of metal catalysts and chemicals with active ionic species, i.e., ionic liquids (IL) and conductive polymers, in our sensing strategy to achieve in situ and real time detection of important chemical and bioanalytes with high temporal and spatial resolution. The simplicity of the demonstrated detection principles could yield forward-thinking solutions to many sensors challenges, especially miniaturized, real-time and continuous sensing that are essential for their integration with engineering advancements such as portable electronics, networked sensing and next-generation monolithic implementation of autonomous sensors with the performance, cost, power, and operational lifetime characteristics to suit a broad range of applications in health, environment and energy applications. Bio Sketch Xiangqun Zeng is currently a distinguished Professor at Department of Chemistry at Oakland University, Rochester, Michigan. She received her Ph.D. in electrochemistry and surface chemistry from State University of New York at Buffalo in 1997. She has been working in the areas of electrochemistry and interface chemistry at solid electrodes, development of new analytical techniques, chemical and biosensors, ionic liquids and conductive polymers for over 20 years. She held eight patents and her lab has published over 100 peer review papers. She is an organizer for the 18th international meeting on chemical sensors in 2021. She is an Editorial Board member of Journal of Electrochemistry and a regular grant and panel reviewer (served on more than 60 grant review panels for US, European and Israel funding agencies). Dr. Zeng has received numerous awards to recognize her contribution including Oakland University’s New Investigator Research Excellence Award (2005), Academic Excellence Recognition awards (2011-2012), International Service Award (2017), Research Excellence Award (2015), Most Active Grant Seeker Awards (2017-2019), President Ora Hirsch Pescovitz Innovation Research Award (2017) and Frank Giblin Lifetime Achievement Award (2020) that is given to the principal investigator with the most funding over the course of a faculty’s career at Oakland University. She has trained over 80 students/postdoc/visiting scholar (24 postdocs, 9 visiting professors including one Fulbright scholar, 12 M.S. thesis and 8 Ph.D. thesis, over 20 undergraduate students, as thesis co-advisor for 5 Ph.D. and 1 M.S. student at other institutions). Seventeen of them are academic professors/scientists in US and other countries and many of them are industry scientists and leaders. Dr. Zeng was featured in a book entitled “Women Who Changed the World the Journey and the Joy” (Sunbury Press Inc. 2015).
