    The research in the Shen lab interfaces between state of art ultra-high resolution nano-electroanalytical chemistry and neurobiology. The main theme of Shen research program is to interrogate chemical, spatial and temporal heterogeneity in biomaterials using chemically-specific nanosensor probes. Currently their efforts are geared towards detecting neurotransmitter release and uptake in/near the synaptic cleft for both electrochemical active and non-active neurotransmitters. Specifically, they are interested in the following research areas:

    Develop nanosensor probes for the multifunctional detection of Neurotransmitters.

    Electroanalytical chemistry has been playing a critical role in studying neurotransmission. Non-redox active neurotransmitters, despite their importance in memory and health, remains largely unexplored. This is due to lack of suitable sensor probes for their detection. Shen lab is developing novel sensor probes that can be used to detect non-redox active neurotransmitters (such as Acetylcholine) employing multi-disciplinary toolsets such as Nanotechnology, Electrochemistry, Interfacial Chemistry. The detection is based on ion transfer across a nanoscopic interfaces between two immiscible electrolyte solutions (ITIES). Besides, these sensor probes developed in the Shen lab can be used to detect redox active neurotransmitters as well.

    Nanometer-resolution imaging of biological processes at single & nano-biostructures.

    Studying neurotransmission at single nano-biostructures have been challenges facing scientists for many years. This is due to limitation in available probes and platforms for performing such measurements as well as resolve the technical challenges set by the size of nanostructures, i.e. synaptic cleft typically has size less than 100nm. Shen lab is employing nanoITIES electrode sensor probes, and nano-resolution Scanning Electrochemical Microscopy imaging platform, to study neurotransmission at this technically challenging yet biologically critical region, Synaptic Cleft.
