Single Step Assembly of Janus Porous Biomaterial by Sub‐Ambient Temperature Electrodeposition (Small 48/2022)

Biomaterial Electro-Fabrication In article number 2204837, Xue Qu, Changsheng Liu and co-workers report a one-step electro-fabrication method at sub-ambient temperatures that organizes the polysaccharide chitosan over a hierarchy of length scales to form a Janus porous hydrogel structure. This water-based fabrication method is simple, rapid and scalable, and allows a tuning of micro-structure (e.g., pore size, porosity and thickness) and macro-morphology (size and shape). This anisotropically-structured hydrogel guides cellular responses to enable bone regeneration.
