Harold Monbouquette, Ph.D., is a Professor of Chemical and Biomolecular Engineering. His group conducts research focused on sensors and diagnostics, as well as the application of nanotechnology to these areas. He has been instrumental in creating an implantable microprobe with neurochemical sensing sites that exhibit rapid response times (<100 msec) while retaining high selectivity, in incorporating multiple sensing modalities on the same probe, in developing a PDMS microstamping method to deposit enzyme to targeted microelectrode sites, and in fabricating an on-probe reference site that results in 60-70% reduction in sensor noise.
