제목 Polyelectrolyte Complex Hydrogel system composed of Chitosan and Poly γ-Glutamic Acid for Controlled Drug Release
초록 Hydrogels are water-swollen polymer networks and in recent years, particular interest has been devoted to hydrogels exhibiting phase transitions (i.e. volume change) in response to changes in external conditions. In particular, polyelectrolyte hydrogels exhibit a discontinuous volume changes in response to pH and ionic concentration as a result of coupling between ionization degree and elasticity. In this study, we have developed a new polyelectrolyte complex system composed of chitosan as positively charged polymer and γ-PGA as negatively charged polymer to control a hydrogel swelling degree by changing two factors, mixing weight ratios and buffer pH.
