Poly amino acids, which are presented in nature have biocompatibility and biodegradability, and are used in various medical and biological application fields such as cell adhesion, drug delivery, gene therapy and diagnostic. There are three different poly amino acids present in nature, poly-γ-glutamic acid(γ-PGA), poly-ε-lysine (ε-PLS), and cyanophycin. Among them, γ-PGA hydrogel has variety applications in medical device, cosmetics, pharmaceutical and environmental industry for its characteristics of biodegradability, non-toxicity, compatibility and edibility. γ-PGA hydrogel with vitamin C was prepared by using crosslinking reaction by chemical crosslinking agents. The structure of crosslinked γ-PGA hydrogel was analyzed. |
