A novel hydrogel formed from a crosslinkable trilayered polymeric micelle and a polyamine is developed for the sustained release of hydrophilic compounds. The hydrogel that is formed from the trilayered polymeric micelles possessing a vesicle-like flexible structure exhibits a higher storage modulus than the hydrogel that is formed from the bilayered polymeric micelles possessing a highly packed, hard structure. The results by Yusuke Uchida, Kengo Fukuda, and Yoshihiko Murakami on page 124 strongly demonstrate that the microscopic structural difference of crosslinkers causes a macroscopic change in the properties of resulting hydrogels.
