Origami of hydrogel bilayers provides robust mircocapsules through anisotropic volume expansion. In their Communication on page 1420 ff., S.‐M. Yang and co‐workers show planar bilayer microparticles composed of active and passive layers that can transform into microcapsules with a closed compartment. The reversible transformation by folding and unfolding of microparticles enables in situ encapsulation and triggered release of micro‐ to nanoscopic encapsulants.
