Detection techniques for singlet oxygen production during photodynamic therapy(Conference Presentation)

Singlet oxygen is widely considered to be the major cytotoxic reactive oxygen species (ROS) generated during photodynamic therapy (PDT). This talk summarizes recent advances and future perspectives in detection techniques for singlet oxygen production, and the advantages and limitations of each technique will be presented. In addition, our custom developed novel configuration of a near-infrared sensitive camera and adaptive optics for in vivo fast imaging of singlet oxygen luminescence around 1270 nm will be highlighted. For clinical PDT application, the challenges for direct measrement of singlet oxygen luminescence will be discussed.
