The use of self-illuminating system as light source provides an intriguing solution to the light-penetration issues of conventional PDT, which have gained considerable research interest in the past few years. This minireview aims to present an overview of self-illuminating PDT systems by using internal light sources (chemiluminescence, bioluminescence, and Cerenkov radiation) and give a brief discussion on the current challenges and future perspectives.
