An efficient platform capable of cell adhesion needs to be developed to understand cell activities such as cell differentiation, diffusion, and migration. The basic sequence of cell adhesion involves cells communicating with their environment by generating mechanical and chemical signals. Thin polymeric films with micro- or nano-patterns are widely used as supports for cell growth with conformal contact at the bio-interface. we developed micro-pattern Nafion films fabricated by a molding process. We present the fabrication and characterization of flexible, micro-patterned Nafion films and the evaluation of cell adhesion and alignment on these films. We found that the cell adhesion and migration/ direction could be modulated by controlling the surface architecture. This approach offers a new platform for a promising tool for use in flexible cell-based platforms and devices to observe cell-cell and cell-surface interactions
