Control of the ordering and orientation of biopolymers has been significant for the well-defined nano- and micro-structures in material sciences and bioengineering. Recently, the formation of liquid crystalline phases using semiflexible biopolymers such as DNA, bacteriophages, and actin filaments have been reported.[1,2] However, still there are many obstacles to overcome to use biopolymers for practical applications.. Here, we produced the aligned liquid crystalline phases based on crude DNA materials extracted from salmon, forming the interesting zigzag structures during assembling process. These unique patterns can be easily fabricated on the flat substrate as well as in the topographic patterns, which were analyzed by polarized optical microscopy (POM) and atomic force microscopy (AFM). WE believe our resultant periodic patterns of DNA materials can provide a hint to use self-assembled biomaterials for the templating applications to guide other micro- and nanomaterials. |
