| Sumario: | In this article, researchers report an approach for generating surface patterns of microscale silica features up to areas of 10 mm² using vesicle arrays as templates at room temperature. The morphologies of silica features, including convex protrusions, concave depressions, and their hierarchical combinations, are controlled synthetically. It is further demonstrated that these surface patterns can function as arrays of microlenses that are capable of producing numerous images from a common object. Researchers believe that their approach is of implications for chemically designing and tailoring hierarchically structured materials with desired functions.
