A scalable photo-initiated crosslinking technique assembles frozen material building blocks into multizonal constructs using di-tyrosine bond formation. Thawing or freeze-drying generates microscale porosity with tunable pore size, shape, and alignment. Demonstrated with silk fibroin and gelatin, the approach yields larger, more stable pores than physical crosslinking, maintains cytocompatibility, and enables covalent immobilization of bioactive molecules for biomimetic, mechanically robust scaffolds suited to aligned tissue engineering.
