The goal of the McCarty Research Group is to improve the biomedical infrastructure for in vivo molecular monitoring and to apply this infrastructure to research on neurological disease treatments. The ability to monitor the biochemical environment and fluctuations in neurochemical levels in vivo is critical to understanding how pharmacological treatments are affecting brain function. Specifically, we plan to advance our existing molecular monitoring technologies, microfabricated interface platforms, by increasing their functionality and to apply the infrastructure to study common neurological treatments, gaining insights into their mechanisms of action. The McCarty Group has developed the technology to make these measurements in vivo. The McCarty Research Group has a broad background in chemistry, physics and engineering which it applies to cutting edge research in biomedical measurements and specifically in molecular monitoring in vivo. Recently the Group’s research emphasis was on creating novel nanostructures and nanotechnologies for molecular monitoring. Currently the McCarty Research Group is collaborating with Dr. R. Mark Wightman and Dr. Leslie Sombers. Both are experts in molecular monitoring in vivo for neuroscience.
