  "abstract": "Endovascular embolization requires materials that can pass through narrow microcatheters yet form stable, conformal occlusions within irregular vascular lesions, but reconciling these competing requirements remains challenging. Here we report a wirelessly activated liquid precursor whose final architecture is constructed only after target localization. A gallium-based liquid metal containing iron microparticles and gas microcavities remains deformable, magnetically navigable, and retrievable before activation. Wireless induction heating activates the internal reactive microenvironment, coupling gas-driven microcavity growth with oxidative mineralization of newly generated gallium interfaces to form a porous, self-supporting scaffold. In aneurysm and arteriovenous malformation models, activation enabled durable occlusion, aneurysm-neck healing, and six-month stability in a porcine aneurysm model. These findings establish post-delivery construction as a strategy for creating stable therapeutic implants from minimally invasive liquid precursors.",
