Recent progress on surface pattern fabrications based on monolayer colloidal crystal templates and related applications.

This review summarizes the recent progress toward the fabrication of surface patterns depending on the monolayer colloidal crystal templates. Based on the structural differences of the acquired surface patterns, various synthesis routes are introduced in detail. The diverse device applications of the synthesized surface patterns are also summarized, including sensors, energy-related devices, field emissions, wettability control, and so on. Future research should focus on surface patterns composed of multiple-layered structures and hybrid materials, and the widening of their application explorations.
