Tuning the Emission of Semiconducting Polymer Dots from Green to Near-Infrared by Alternating Donor Monomers and Their Applications for in Vivo Biological Imaging.
Detection of reactive oxygen species (ROS), a hallmark of many pathological processes, is imperative to understanding, detection and treatment of many life-threatening diseases. However, methods capable of real-time in situ imaging of ROS in living animals are still very limited.
This paper described the energy-transfer amplified singlet oxygen generation in semiconductor polymer dots (Pdots) for in vitro and in vivo photodynamic therapy. Hydrophobic photosensitizer tetraphenylporphyrin was facilely doped in the nanoparticles consisting of densely packed semiconductor polymers. Optical characterizations indicated
