My research interests are in the field of sensor technology. More specifically, we are interested in utilizing modern electrochemical techniques to monitor transport across thin membranes. One project involves the use of nanochannels (from 5 to 100nm in diameter) made of gold or alumina. The channels have native size selectivity, much like a filter. However, chemical selectivity can be induced by further functionalizing the nanochannels (via Au-thiol and alumina-silane chemistries). Another project is focused on novel ion-selective electrodes (ISEs) that can monitor the concentration of one ion in a larger mixture (such as fluoride in drinking water). Our group synthesizes and examines a wide variety of metal chelators and organometallic compounds that are utilized in these sensors.
