Hydrogel based on fish-derived gelatin was prepared by electron beam (EB) irradiation under the linear accelerator in TARRI, QST, Japan. The elastic modulus of the gelatin gels prepared at concentration of 30 wt.% solution by EB irradiation with the doses from 20 to 100 kGy were 100 – 500 kPa, which are suitable for the use as bio-materials. |
