Light-triggered release of drug conjugates for an efficient combination of chemotherapy and photodynamic therapy.

Herein, we present a series of light-triggered porphyrin-based polymeric drug conjugates PSDTD-m for combined chemo-photodynamic therapy of cancer. The controlled release of a drug through a ROS-cleavable linker combined with photodynamic therapy showed enhanced anticancer efficacy, proving the effectiveness of this light triggered smart nanocarrier platform for enhancing the therapy efficacy.
