Threshold‐Gated DNA Nanocages Enable Programmable Quorum‐Like Sensing in Vesicle Communities

generated by a GOX-CAT positive-feedback circuit as the autoinducer, we achieved density-dependent signal accumulation and threshold-triggered reversible structural switching, thereby exhibiting key operational features of quorum-like sensing in vesicle-based communities. This platform provides a general model for studying community organization and cooperative behaviors, with potential applications in biomimetic sensing, programmable smart materials, and stimulus-responsive delivery systems.
