Role of metal nanoparticles and patterned composites on enhancing electrical trace gas sensing


EMSL Project ID
42314

Abstract

This proposal seeks to utilize the fabrication and characterization resources at EMSL under the general proposal category for understanding the role of metal nanoparticles in patterned composites in enhancing the measured signal strength of trace chemical sensors through the phenomena of nanoscale confinement. Metal nanoparticles will be embedded into electro active polymers which will then be lithographically fabricated onto silicon based metallic structures to develop electrical/electrochemical sensors. The resources at EMSL will be utilized to evaluate the role of the nanoparticles in enhancing the electro active polymer behavior as a trace gas sensor. The density, distribution and morphology of the nanoparticle embedded polymer will be characterized at the EMSL capabilities and will be correlated to the sensor performance testing that will be performed at WSU.
