Dr. Christopher Muratore, Ohio Research Scholars Endowed Chair Professor in the Chemical and Materials Engineering Department at the University of Dayton will give a seminar to interested students and faculty at Discovery Park.

Abstract

Materials with high surface-to-volume ratios demonstrate exquisite sensitivity and detection limits in diverse molecular sensing applications.  Integration of nanowires, nanotubes, and two-dimensional (2D) semiconductors into sensing devices, however, presents challenges inhibiting development of products based on these materials.  To realize applications of 2D transducers in ubiquitous low-cost diagnostic devices, new fabrication approaches are required. Processes for high-rate (>106 per day) mass-production of low-cost two-dimensional electronic medical diagnostic devices with limits of detection rivalling PCR will be presented. Processing methods allow for control of binding site density and adjustable dynamic range of sensor devices.  Response times for most analytes are 2 minutes or less, and detection of multiple analytes on an array of sensors fabricated on a single flexible chip is straightforward.  A large supply of unfunctionailzed diagnostic devices manufactured in this way may be stored to be functionalized with any selective binding agent on-demand to immediately reduce the impact of future disease outbreaks.  Materials for large-scale device fabrication were selected to ensure recyclability of the devices for reduced waste stream impact in anticipation of large numbers of devices are consumed daily.

Biography

Christopher Muratore is the Ohio Research Scholars Endowed Chair Professor in the Chemical and Materials Engineering Department at the University of Dayton. Prior to joining the University, Professor Muratore spent 9 years as a scientist at the Air Force Research Laboratory and still works closely with multiple sensor and flexible electronics groups there and industry partners. Throughout his 22 year research career, Christopher’s work has focused on developing an understanding of how to control structure and properties of transition metal dichalcogenides and other thin films and surfaces for optimization of properties and performance in diverse applications from high-performance aerospace engines to healthcare. He has several patents awarded, with more than ten pending related to new medical diagnostic sensor work. Chris also has published over 100 peer-reviewed articles and has served as guest editor for several journals. He is also a Fellow of the American Vacuum Society. Prior to his work at AFRL, he was an ASEE Research Fellow at the US Naval Research Laboratory in Washington, DC. Christopher has a Ph.D. in Materials Science and Engineering from the Colorado School of Mines.
