  • Chemical sensors have become a valuable method for the detection and quantification of a multitude of analytes. The ideal sensor and sensor system would be portable, inexpensive, readily fabricated, and monitor and quantify several key analytes both simultaneously and reversibly. The dissertation focuses on the development of new generation photonics-based chemical sensors and sensor systems by exploiting the benefits from sol-gel processing technology, pin printing methods, and low-power detection schemes. There are three main topics within this work. First, we describe techniques to provide a diverse sensor response to an analyte. Secondly, we describe the development of a compact sensor system. Lastly, we improve multianlayte sensing capabilities through advancements in material...
