光动力疗法(Photodynamic Therapy, PDT)是结合光和光敏药物治疗肿瘤和皮肤性病的新方法，具有创伤小、选择性好、适用范围广、非侵入性等特点。
?激发波长处于最佳“生物光学窗口”（700-850 nm）, 组织穿透深度可达到10 mm左右，高反应活性
Photodynamic Therapy (PDT) is a new treatment of tumor and skin diseases by combining light and photosensitizing drugs，which features small trauma (even non-invasiveness), good selectivity and wide application range.
?Excitation wavelength at "bio-optical window" (700-850 nm), the tissue penetration depth up to 10 mm, and high PDT reactivity
?Original bio-orthogonal technology: improve drug targeting and potential for precise treatment
?In situ monitoring the treatment process combing imaging and PDT
We aim to develop a series of prototypes of photosensitizers with high photosensitivity, wide near-infrared window and high penetration depth, which are perspective to overcome the key issues of photosensitizers occurring in clinical PDT applications.
