Photodynamic Therapy

Group Leader: Quian Peng Ph.D.

Photodynamic therapy (PDT) is a two-step therapeutic technique in which the topical or systemic delivery of a photosensitizing drug is followed by irradiation with visible light. The activated photosensitizer transfers energy to molecular oxygen, generating reactive oxygen species (ROS). The subsequent oxidation of lipids, amino-acids and proteins induces cell necrosis and apoptosis. This group has been working on the projects of PDT for more than 10 years.
