Understanding and controlling the surface properties of bioscaffolds are crucial for regulating cell adhesion proliferation behaviors. We here focused on poly(vinylidene fluoride) (PVDF), in which polymer chains oriented through poling treatment to form a polar β-form crystal. The aggregation states uniaxially stretched PVDF films subjected were investigated based water contact angle measurements sum-frequency generation spectroscopy. During under sufficiently strong electric field, dipole moments crystals, inherently aligned within each crystalline domain, become more uniformly across entire film. As result, resists structural reorganization even upon exposure water. This stable surface, maintains its despite environmental changes, was found promote proliferation, as well protein adsorption. Our findings contribute deeper understanding relationship between scaffold surfaces interactions, ultimately advancing insights into

Efforts in cartilage tissue engineering to repair injuries have seen limited success, primarily due the inability of scaffold materials establish a microenvironment conducive extracellular matrix (ECM) deposition by chondrocytes. Hydrogels, which mimic human tissue, are commonly employed as materials; however, their constrained network structure and low bioactivity impede chondrocyte ECM deposition, complicating repair. In this study, we developed dynamic Col-HZ hydrogels featuring adaptive networks forming hydrazone (HZ) bonds between bioactive natural collagen synthetic polyethylene glycol (PEG). contrast static that rely on covalent bonds, facilitate migration deposition.
