The disclosure relates to an expandable scaffold and a method for fabricating the scaffold. The expandable scaffold includes a three-dimensional porous structure comprising a composite material composed by a first material and a second material. The 3D porous structure has a tunable expansion capacity. When applied in a liquid, the 3D porous structure may uptake the liquid and expand from an original volume to an expansion volume up to 1000 times of the original volume. The 3D porous structure may be formed by a plurality of layers of the composite material, and architecture and shape of the layers of the composite material are arranged in accordance with a shape and a size of the expansion volume. Applications of the scaffold may include a bone or soft tissue regeneration system or a bleed stopping device.

Expandable bone and tissue regeneration system, and applications of same

A method for forming a biocompatible structure includes the steps of forming a layered structure having alternatively disposed first layers and second layers, where the first layers includes at least one polymer and first particles, and the second layers includes second particles; and treating the layered structure with a washing solvent to form the biocompatible structure, where the first particles are solvable in the washing solvent.
