In the last few decades, polysaccharide and protein hydrogels have attracted significant
attentions and been applied in various engineering fields. Polysaccharide and protein
hydrogels with appealing physical and biological features have been produced to meet different
biomedical applications for their excellent properties related to biodegradability, biocompatibility,
nontoxicity, and stimuli responsiveness. Numerous methods, such as chemical
crosslinking, photo crosslinking, graft polymerization, hydrophobic interaction, polyelectrolyte
complexation and electrodeposition have been employed to prepare polysaccharide and
protein hydrogels. Electrodeposition is a facile way to produce different polysaccharide and
protein hydrogels with the advantages of temporal and spatial controllability. This paper reviews
the recent progress in the electrodeposition of different polysaccharide and protein hydrogels.
The strategies of pH induced assembly, Ca2+ crosslinking, metal ions induced assembly,
oxidation induced assembly derived from electrochemical methods were discussed. Pure,
binary blend and ternary blend polysaccharide and protein hydrogels with multiple functionalities
prepared by electrodeposition were summarized. In addition, we have reviewed the applications
of these hydrogels in drug delivery, tissue engineering and wound dressing.
