Nature has a remarkable ability to create diverse functional structures through self-assembly process. Although recent advance of direct self-assembly enables to organize small molecules into sophisticated functional structures, the functional and structural complexity does not compare to that of natural systems. Here, we have developed a novel biomimetic directed-self-assembly process which closely mimics the natural self-assembly processes. By using M13 bacteriophage as a model helical nanofiber, intermolecular interactions at the meniscus of a dip casted substrate were exploited to guide the self-assembly of phages into three-dimensionally functional nanostructures. These micro-patterns also exhibited exquisite optical properties, such as structural color and optical switching behaviors. Our multi-dimensional assembly process can be expanded to the directed self-assembly of many other colloidal particles for constructing three dimensionally ordered structures. |
