Abstract
This chapter presents the basic sciences involved in photodynamic therapy, in terms of: the photophysical, photochemical and photobiological principles; the technologies of PDT light sources, delivery systems and dosimetry devices; and optical methods that are under development for monitoring the response of tissue to PDT. The current and potential medical applications are also indicated. The discussion includes both aspects of PDT that are well-established and new concepts in the science, technology or clinical applications, including work from the author's laboratory.
