Abstract

This chapter describes fundamental properties of molecular photochemistry including photochemical and photophysical processes, general information about light sources, and the overview of light technology in biomedical research. The topics in photochemistry include the basics of energy diagram, electronic structures, light absorption and fluorescence, electron and energy transfer, and photo-sensitizing properties. This chapter also describes utilization of light sources in photochemistry such as mercury arc lamps, a xenon lamp, light-emitting diodes as incoherent light sources, and lasers as coherent light sources. We review light technology for biomedical applications: photodynamic therapy and Photopharmacology for medicinal applications, laser scalpel and laser skin resurfacing for surgical applications, and optoporation for drug and gene delivery applications. We also briefly introduce a fascinating research topic of light therapy for treatment of psychotic depression and sleep disorder.
