In this study, we present a versatile and scalable self-assembly approach for encapsulating cargo particles within well-defined porous membranes or cages. The encapsulation process involves camouflaging cargo within a liquid matrix that serves as a scaffold for satellite particles to form densely packed shells around. These satellites fuse to create self-standing cages, after which the liquid matrix is dissolved, trapping the cargo inside. By adjusting the fusion protocol, we can control the porosity of the cages at various length scales. We demonstrate the potential of this technique by employing functional cargo to showcase transmembrane transport phenomena, such as the delivery and active uptake of nanoparticles. 000013479 536__ $$oU.S. Army Research Office$$cW911NF2010117 000013479 540__ $$a<p>© 2023 The Authors.</p> <p>This publication is licensed under <a href="https://creativecommons.org/licenses/by/4.0/">CC-BY 4.0</a>.</p> 000013479 542__ $$fCC BY 000013479 690__ $$aPhysical Sciences Division 000013479 691__ $$aEnrico Fermi Institute 000013479 691__ $$aPhysics 000013479 692__ $$aJames Franck Institute 000013479 7001_ $$1https://orcid.org/0000-0002-8599-079X$$2ORCID$$aXu, Zhe$$uNew York University 000013479 7001_ $$1https://orcid.org/0000-0002-4474-6280$$2ORCID$$aHueckel, Theodore$$uNew York University 000013479 7001_ $$1https://orcid.org/0000-0002-4925-2060$$2ORCID$$aIrvine, William T.
