What is the context?1. Platelets were applied to load IO-PG-DOX-Ce6, wherein the laser-triggered drug release and anti-tumor effect were investigated in vitro.2. The findings indicated that IO-PG-DOX-Ce6 could be stably loaded by platelets in high volume without any decrease in viability, which may attribute to the activation of autophagy in platelets.3. IO-PG-DOX-Ce6-loaded platelets could be significantly activated by laser irradiation (690 nm).4. Activated platelets released extracellularly their cargo drug after laser exposure, which could be taken up by co-cultured tumor cells5. The co-culture model of drug-loaded platelets and tumor cells proved that the laser-triggered delivery system of platelets could effectively damage the DNA and promote apoptosis of tumor cells.What is new?1. Platelets could be utilized as the vehicle to load photosensitizer-loaded-nano-drug.2. Photodynamic action can activate platelets in a spatiotemporally controlled manner, which could be a tool to regulate the activation of platelets.3. The laser-triggered activation of drug-loaded platelets allows for target release of cargo.4. The limitation of the current research is that only in vitro experiments were carried out to demonstrate our conclusions.What is impact?The present work provides a novel and feasible approach for the clinical application of cytopharmaceuticals.
