Figure Lengend Snippet: ( A ) Synthesis process of an NCG. (PFH, liquid-gas phase-change core; PDA, stabilizer; FA, solid-liquid phase-change shell) capable of gas-liquid-solid triphasic conversion. ( B ) Schematic of the strategy for NCG-triggered nanocollision for enhanced locomotion of DCs. First, ultrasound induces vaporization of PFH. Then, the gasified PFH generates a critical internal pressure, triggering instantaneous rupture of the FA shell with subsequent outward ejection of fragmented particulates. Subsequently, the fragmented particulates induce nanocollisions with DCs, eliciting localized fluctuation of plasma membrane. IV, Piezo1 detects the fluctuation and mediates Ca 2+ influx through its central pore. Finally, Ca 2+ influx induces F-actin polymerization (enhanced intrinsic locomotion) and high expression of CCR7 (enhanced chemotaxis). ( C ) Locomotion-enhanced DCs potentiate antigen capture and lymph node homing, thereby activating T cells to amplify antitumor immunity.
