Cellular interactions on synthetic and natural materials have been used to understand cell behaviors including adhesion, proliferation, differentiation and movement. Here we present the study of cellular interactions on polymer surfaces where platinum (Pt) nanoparticles are localized as micro-patterns. Pt nanoparticles are highly attractive material in electro-active membrane and device technology. In this study, we demonstrate a convenient method to synthesize Pt nanoparticles by using the nano-structured polymeric films. These polymer films are polyelectrolyte multilayers that are assembled by electrostatic force or hydrogen bonding interactions. These nanoparticle-embedded films were used for studying electrical properties and cellular responses on their surfaces. In addition, we created micro-patterns of Pt nanoparticles which selectively placed on the polymer films using micro-contact printing technique. |
