Recent Advances of Photoactive Near-Infrared Carbon Dots in Cancer Photodynamic Therapy

Pharmaceutics, 2023
Photodynamic therapy (PDT) is a treatment that employs exogenously produced reactive oxygen species (ROS) to kill cancer cells. ROS are generated from the interaction of excited-state photosensitizers (PSs) or photosensitizing agents with molecular ...

Genetically Encoded Photosensitizers as Light-Triggered Antimicrobial Agents [PDF]

International Journal of Molecular Sciences, 2019
Diseases caused by multi-drug resistant pathogens have become a global concern. Therefore, new approaches suitable for treating these bacteria are urgently needed. In this study, we analyzed genetically encoded photosensitizers (PS) related to the green fluorescent protein (GFP) or light-oxygen-voltage (LOV) photoreceptors for their exogenous ...

Multifunctional Photosensitizer-Based Contrast Agents for Photoacoustic Imaging [PDF]

Scientific Reports, 2014
Photoacoustic imaging is a novel hybrid imaging modality combining the high spatial resolution of optical imaging with the high penetration depth of ultrasound imaging. Here, for the first time, we evaluate the efficacy of various photosensitizers that are widely used as photodynamic therapeutic (PDT) agents as photoacoustic contrast agents ...
