Modulation of cell behaviors by electrochemically active polyelectrolyte multilayers

Abstract: In addition to the topographical features and chemical properties of substrates, the mechanical properties are known as a vital regulator of cellular processes such as adhesion, proliferation, and migration, and have received considerable attention in recent years. In this work, electrochemical redox multilayers made of ferrocene-modified poly (ethylenimine) (PEI-Fc) and deoxyribonucleic acid (DNA) with controlled stiffness were used to investigate the effects of the mechanical properties of multilayers on fibroblast cell (NIH/3T3) behaviors. Redox PEI-Fc plays an essential role in inducing swelling in multilayers under an electrochemical stimulus, resulting in distinct changes in the stiffness of the multilayers. The Young’s modulus varied from 2.05 to 1.07 MPa for the (PEI-Fc/DNA) multilayers by changing the oxidation time of the electrochemical treatment. We demonstrated that the adhesion, proliferation, and migration of fibroblast cells depended on the multilayers’ stiffness. These results indicate that cell behaviors can be precisely controlled by electrochemical treatment, which provides a new way to prepare thin films with tunable mechanical properties with potential biomedical applications.
