Cathodic electrodeposition of chitosan. (a) Chitosan deposition (i.e. self-assembly) is induced by the high pH generated by cathodic electrolysis reactions. (b) Molecular modeling shows the pKa of an individual glucosamine residue is lowered when it is buried within the crystalline domains that serve as the physical network junctions (i.e. crosslinks).

(c) When an oscillating electrical input sequence is used to cue chitosan’s electrodeposition, the resulting hydrogel has a segmented internal structure that is controlled by the input sequence.
