Chitosan-based self-healing hydrogel for bioapplications

By using an easily available PEG derivative and biopolymer chitosan, a self-healing hydrogel has been facilely prepared through the dynamic Schiff base. This biocompatible self-healing hydrogel can be used for drug-delivery, 3D cell culture and as a basic platform to develop some organic-inorganic biohybrids. This mini-review summarized recent research about that chitosan based self-healing hydrogel and related materials, and discussed some future bio-applications of that hydrogel (C) 2017 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
