Nano Materials Coating for Plasmonic Chemical Gas Sensors
Please register to receive the link to the event.
The motivation behind this work is to build a chemical gas sensor that can be sensitive and selective using optical nano Plasmonic sensor. Optical Nano Plasmonic sensors are devices that are designed with their resonance frequency in the visible range. The basic principle governing the sensing mechanism for optical Plasmonic sensor is the refractive index sensing. The changes in the refractive index of the environment around the plasmonic sensor led to the change in the resonant frequency of the sensor. This inherent property of the device makes it extremely selective to different gases since different gases have different refractive index. In this work, we use this inherent quality of the Nano Plasmonic sensor as being selective and have developed different Nano material coatings for different plasmonic sensors. Our techniques make these devices more sensitive and selective to different chemical gas molecules.

Nano Materials Coating for Plasmonic Chemical Gas Sensors
Abstract:
The motivation behind this work is to build a chemical gas sensor that can be sensitive and selective using optical nano Plasmonic sensor. Optical Nano Plasmonic sensors are devices that are designed with their resonance frequency in the visible range. The basic principle governing the sensing mechanism for optical Plasmonic sensor is the refractive index sensing. The changes in the refractive index of the environment around the plasmonic sensor led to the change in the resonant frequency of the sensor. This inherent property of the device makes it extremely selective to different gases since different gases have different refractive index. In this work, we use this inherent quality of the Nano Plasmonic sensor as being selective and have developed different Nano material coatings for different plasmonic sensors. Our techniques make these devices more sensitive and selective to different chemical gas

Biography:
Professor Mona E. Zaghloul, earned her PhD in Electrical Engineering from the University of Waterloo, Canada, in 1975. She was the first woman to graduate with PhD in Engineering from U of Waterloo. She Joined The George Washington University in 1980 and became a Full Professor in 1989, and the Department Chair of the Department of Electrical Engineering and Computer Science in 1994-1998, and in 2009-2014. During her tenure at GWU, Dr. Mona Zaghloul served as a Program Director in the Division of Electrical Communication and Cyberspace Systems of the National Science Foundation (NSF), and as a Faculty Hire and Sabbatical Researcher at NIST, ARL (Army Research Laboratory), NASA in the US, and at the Technical University of Delft in the Netherlands. In 2017 she was elected member of the National Academy of Inventor; she is a Fellow of NAI.
Her publications (she published over 360 papers), several patents, teaching, and research, as well as her professional service at the IEEE, have helped to create the scientific foundation for Sensors, MEMS/NEMS systems that led to the establishment of the Institute for MEMS and VLSI Technologies at GWU. She published widely in those and other areas and became a Life Fellow of IEEE, Fellow of the National Academy of Inventors, and the IEEE Circuits and Systems Jubilee Golden Medal awardee in recognition of her pioneering work. She was the IEEE Sensors Council President (2009-2010) and received Honorary Doctor Degree from University Waterloo, Canada in 2007.
