This invention provides a preparation, composition, product, and application of a photo-coupled synergistically crosslinked hydrogel material. The preparation includes dissolving Component A including a photosensitive polymer derivative having o-nitrobenzyl phototriggers and Component B including a polymer derivative having amine or alkene (double group) or sulfhydryl group in a biocompatible medium to obtain solution A and solution B, respectively; mixing the solution A and solution B homogeneously to obtain a hydrogel precursor solution; initiating photo-coupled synergistic crosslinking under an irradiation of a UV light to form the hydrogel. The irradiation causes the o-nitrobenzyl phototriggers to generate an aldehyde group/keto group or a nitroso group to initiate photo-coupled synergetic crosslinking. The photo-coupled synergistically crosslinked hydrogel has applications in tissue engineering, regenerative medicine, 3D printing and as a carrier of cell, protein or drug.

A load-bearing bone fixation composite includes a polymer matrix, a plurality of polymer fibers aligned along a common axis and disposed in the polymer matrix, wherein the polymer matrix binds the surface of the polymer fibers, and a plurality of high aspect ratio nanorods coating at least a portion of each of the polymer fibers, wherein the long axis of at least a portion of the nanorods is aligned with the common axis, and wherein the high aspect nanorods have an aspect ratio of 10 or greater. Further included is a bone fixation device including the foregoing composite. A method of bone fixation comprises affixing the foregoing composite to a site of a load-bearing bone fracture, or maxillofacial bone fracture. Also included are methods of making the composites.
