Interests

My interests are fluorescent probe and photosensitizer (PS) development, fluorescence imaging, photodynamic therapy (PDT), multi-functional drug delivery system, and intraoperative imaging. Our lab develops targeted molecular probes for cancer imaging and therapy purposes.

Projects

The goal of our laboratory is to develop and evaluate new molecular probes for diagnostic imaging and therapy, particularly fluorescence imaging agents and PSs with the ultimate goal of moving our basic science discoveries to the clinic. Fluorescence imaging is a powerful technique for location of tumors and identification of tumor margins in the clinic. It is also often used to label specific proteins to study the precise role of these proteins in the regulation of physiological activities and diseases. The success of such applications largely depends on highly sensitive and specific fluorescent probes, which we are interested in developing and evaluating (in vitro and in vivo) in our lab. Another aspect of our research is to synthesize near infrared (NIR) PSs for PDT of cancers in a target-specific, minimally invasive, and highly controllable manner. Because PSs only produce phototoxicity in the irradiated area, PDT treatment avoids systemic toxicity. In addition, the intrinsic fluorescence of PS allows for fluorescence imaging-guided therapy, offering PDT a desired "see and treat" approach. Targeted NIR PSs have great potential to treat tumors with high efficacy and low side effects, as well as providing fluorescence imaging guidance with high contrast.
