In Vitro Photoirradiation System for Simultaneous Irradiation with Different Light Doses at a Fixed Temperature.

Objective: In this work an irradiance and temperature controlled in-vitro system for conducting investigations in PDT and phototherapy is presented.

Background Data: The development of new light sources has caused a considerable increase in research and application of several photodynamic (PDT) therapeutic methods, as well as other light-based therapeutic techniques. However, further work is needed to fully understand and elucidate the mechanisms as well as to increase the effectiveness of PDT.
