DNA has recently emerged as a building block shows liquid crystalline phase depending on the concentration. Controlling orientation of DNA molecules is actually necessary for forming the micro- or nanostructures. Therefore, we developed a technique to control the orientation of particles in a thin film by using evaporation-induced self-assembly and bulk elastic properties of DNA liquid crystal phase. Here, we conducted the evaporation-induced experiments on square-lattice micro-post substrates to form novel and sophisticated DNA nanostructures. The pattern of the DNA within post arrays can be modulated by pulling direction and post spacing. This will help to understand the self-assembly of DNA molecules in confinement effect and can provide applications to bio-template for polymers, liquid crystals or other nanoparticles. |
