Chemical sensors serve as an interface between biological and electronic systems.
We are interested in optimizing the performance of these sensors, designing methods to understand and evaluate their performance, integrating the electronic control system for the sensor onto the substrate and studying the performance of these systems in vivo . REU students have contributed significantly to projects related to these goals, and we hope they will continue to do so through several projects in the future. These projects include using a chronoamperometric method developed in our laboratory to assess the loss of two sensor components upon exposure to blood and tissue, investigating the use of more biologically compatible polyurethanes as sensor membrane materials, and using current polarization across the sensor membrane to lower the detection limit of the sensor.
