Through billions of years of evolution, nature has optimized the programmed assembly of the nano- and micro-scale structures of biological materials. Nanoparticle assembly provides an avenue for mimicking these multiscale functional structures. Bio-inspired surfaces with special wettability have attracted much attention for both fundamental research and practical applications. In this review, we focus on recent progress in nanoparticle assembly-induced special wettability, including superhydrophilic surfaces, superhydrophobic surfaces, superamphiphobic surfaces, stimuli-responsive surfaces, and self-healing surfaces. A brief summary and an outlook of the future of this research field are also provided.
