  • Research

    Professor Chan is currently working on the development of responsive imaging agents known as activity-based sensing probes. He uses a unique approach to detect a specific disease biomarker or biological analyte of interest known as activity-based sensing. In contrast to traditional binding-based approaches (e.g., appending an imaging agent to an antibody that targets a protein), he leverages unique chemistry of the target analyte for sensing. This approach allows him to tune the reactivity of his probes to detect fleeting species by accelerating the reaction or to attenuate reaction rates for biomarkers that are highly abundant. Chan has also coupled sensing to a variety of imaging modalities including fluorescence, bioluminescence, and photoacoustic imaging. He has used the chemical tools for diagnostic applications such as the development of a photoacoustic imaging-based companion diagnostic agent for cancer and a biopsy-free assessment method for elevated hepatic copper in Wilson’s disease. His goal is to expand his activity-based sensing design approach to developing probes for other imaging modalities including ultrasound, PET, SPECT, and MRI.
