We prepared several types of hydrogel using poly-γ-glutamic acid (γ-PGA). γ-PGA is naturally synthesized by Bacillus subtilis (chungkookjang), and it is biodegradable. Naturally occurring polymers have attracted considerable interest among polymer scientists in recent years. γ-PGA hydrogel could be used as compatible biomaterials for many applications. γ-PGA hydrogel by γ-irradiation showed individual specific water content and fast swelling property. They have cross-linked networks and pore structures of various sizes. It is able to regulate physical property of hydrogel by degree of γ-irradiation and molecular weight of γ-PGA. Also, we prepared chemical cross-linked gel and physical gel using by γ-PGA. These each have different physical characteristics. γ-PGA hydrogel may be used as functional cosmetics material, biomedical material, and so on. This indicates that γ-PGA hydrogel could be used in the various fields of industrial application. [This work was supported by the 'Seoul R&BD Program (10580)’]
