Alkaline Phosphatase (ALP), an enzyme involved in mineralization of bone, was incorporated into three hydrogel biomaterials to induce their mineralization with calcium phosphate (CaP). These were collagen type I, a mussel protein-inspired adhesive consisting of PEG substituted with catechol groups, cPEG, and the PEG-fumaric acid copolymer OPF. After incubation in calcium glycerophosphate (Ca-GP) solution, FTIR, EDS, SEM, XRD, SAED, ICP-OES and von Kossa staining confirmed CaP formation. The amount of mineral formed decreased in the order cPEG > collagen > OPF. Mineral:polymer ratio decreased in the order collagen > cPEG > OPF. Mineralization increased Young’s modulus, most profoundly for cPEG. Such enzymatically mineralized hydrogel-CaP composites could find application as bone regeneration materials.
