Bioinspired three-dimensional network hydrogel based on polysaccharides

Hydrogels are hydrophilic colloids with a three-dimensional network. Hydrogels can change their morphology under external stimulation, so they have broad application prospects in the fields of sustained-release drugs, flexible devices and sensors. Inspired by mussel chemistry, the dopamine oxidation self-polymerization reaction was used to solve the problem of instability of nanomaterials in solution. At the same time, we designed a variety of hydrogels based on polysaccharides and micro-nanomaterials, in which surface chemical / physical modification can be expanded the application of hydrogels in the field of biomedicine; the ordered network structure gives hydrogels the characteristics of slow release, self-healing properties and high strength.
