Abstract
Provided herein are composite scaffold biomaterials including two or more scaffold biomaterial subunits, each including a decellularized plant or fungal tissue from which cellular materials and nucleic acids of the tissue are removed, the decellularized plant or fungal tissue having a 3-dimensional porous structure, the two or more scaffold biomaterial subunits being assembled into the composite scaffold biomaterial and held together via gel casting using a hydrogel glue; via complementary interlocking geometry of the two or more scaffold biomaterial subunits; via guided assembly based biolithography (GAB); via chemical cross-linking; or any combinations thereof. Methods for producing such scaffold biomaterials, as well as methods and uses thereof, are also provided.
