Buckling like a 'pop-up book' (VIDEO)

Northwestern University

Caption

Northwestern team designed a soft, porous scaffold that begins as a flat, rubbery lattice and then transforms into a precisely engineered 3D shape. A controlled mechanical buckling drives the transformation — the same mechanism that causes flat paper to convert into 3D structures in a “pop-up” book. This framework gently envelopes the organoid, matching its curvature.
