Erin Gross , PhD

Associate Professor
Analytical Chemistry

My research interests involve novel applications of microelectrodes in analytical chemistry.  As the field of analytical chemistry progresses toward smaller scales and studies in micro-environments, microelectrodes have proven to be compatible detection devices.  The application in which I am most interested is investigating electrogenerated chemiluminescent (ECL) reactions at microelectrodes.  In an ECL experiment, a microelectrode is used to very quickly (microsecond or less time frames) generate the reagents required for chemiluminescence.  Because of its small background and specificity, ECL is ideal for analytical detection.  When coupled with microelectrodes, ECL efficiency is greater and small-scale experiments can be designed.  Ultimately, I would like to use the ECL reactions studied in my laboratory for detection in capillary electrophoresis and microchip applications.
