Ordered micro/nanostructured arrays based on the monolayer colloidal crystals

Besides the traditional lithographical techniques to fabricate the ordered mciro/nanostructured arrays, the route of the monolayer colloidal crystal template is a recently promising, alternative process for the synthesis of the micro/nanostructures with different designed morphologies. By this strategy, two-dimensional ordered arrays, e.g., nanoparticle arrays, pore arrays, nanoring arrays, nanobowl arrays, hollow sphere arrays, etc., even one-dimensional nanostructures of ordered nanorod/nanopillar/nanowire arrays, etc., could be prepared. Recent progress in this area is reviewed, including synthesis strategies and morphology-dependent properties of the micro/nanostructured arrays such as optical properties, wettability, surface-enhanced Raman scattering, and photonic bandgap.
