“…Aizenberg et al synthesized the structural features of Namib desert beetle , cactus spine and pitcher plant together to obtain a rationally designed surface with slippery asymmetric bumps, which achieved unprecedented droplet condensation and transport. Inspired by redbud leaves, Zhong et al designed a water collector in which the skeleton is an ultracontrasting wettability venation network with hierarchical micro‐/nanostructures, and the structural features of Namib desert beetle and cactus were integrated (Figure g–j). While the beetle and cactus‐inspired structures in this work promised the water harvest efficiency, the overall configuration inspired by leaf vein sharply enhanced the speed of water transport.…”

Understanding the relationship between liquid manipulation and micro‐/nanostructured interfaces has gained much attention due to the wide potential applications in many fields, such as chemical and biomedical assays, environmental protection, industry, and even daily life. Much work has been done to construct various materials with interfacial liquid manipulation abilities, leading to a range of interesting applications. Herein, different fabrication methods from the top‐down approach to the bottom‐up approach and subsequent surface modifications of micro‐/nanostructured interfaces are first introduced. Then, interactions between the surface and liquid, including liquid wetting, liquid transportation, and a number of corresponding models, together with the definition of hydrophilic/hydrophobic, oleophilic/olephobic, the definition and mechanism of superwetting, including superhydrophobicity, superhydrophilicity, and superoleophobicity, are presented. The micro‐/nanostructured interface, with major applications in self‐cleaning, antifogging, anti‐icing, anticorrosion, drag‐reduction, oil–water separation, water collection, droplet (micro)array, and surface‐directed liquid transport, is summarized, and the mechanisms underlying each application are discussed. Finally, the remaining challenges and future perspectives in this area are included.

With the explosive growth of the world’s population and the rapid increase in industrial water consumption, the world’s water supply has fallen into crisis. The shortage of fresh water resources has become a global problem, especially in arid regions. In nature, many organisms can collect water from foggy water under harsh conditions, which provides us with inspiration for the development of new functional fog harvesting materials. A large number of bionic special wettable synthetic surfaces are synthesized for water mist collection. In this review, we introduce some water collection phenomena in nature, outline the basic theories of biological water harvesting, and summarize six mechanisms of biological water collection: increased surface wettability, increased water transmission area, long-distance water delivery, water accumulation and storage, condensation promotion, and gravity-driven. Then, the water collection mechanisms of three typical organisms and their synthesis are discussed. And their function, water collection efficiency, new developments in their biomimetic materials are narrated, which are cactus, spider and desert beetles. The study of multiple bionics was inspired by the discovery of Nepenthes’ moist and smooth peristome. The excellent characteristics of a variety of biological water collection structures, combined with each other, are far superior to other single synthetic surfaces. Furthermore, the main problems in the preparation and application of biomimetic fog harvesting materials and the future development trend of materials fog harvesting are prospected.

“…[ 86 ] Micro‐ to millimeter‐scale chemical patterns combined with nanoscale roughness were also explored for applications within dew harvesting. [ 66,68 ] Finally, Mondal et al. were particularly inventive at the millimeter scale as they created their chemically and topographically patterned surface by piercing a hydrophobic sheet with an array of hydrophilic needles (Figure 3c‐iii)—a simple but effective approach.…”

reproducible outcomes are not guaranteed and experiments at this small scale are difficult to characterize. Transcending the randomness would have immense environmental, safety, and economic consequences.A critical element in understanding condensate behavior is the distinction between homo-and heterogenous nucleation. The former case describes a spontaneous nucleus formation in the gas phase, a process that is typically orders of magnitude less likely to occur than its heterogenous counterpart, where nucleation happens at a solid-gas or liquid-gas interface. [8] Therefore, heterogeneities in the system can serve as trigger points for nucleation and deliberate positioning of interfaces can shift the condensation toward specific and predetermined locations. Introducing such nucleation catalysts to alter the random nature is the focus of this review; more popularly phrased, I answer the question: what are the options to achieve spatial control of condensation? Within each category, I discuss its strengths and limitations, with consideration to the degree of control possible and practical considerations such as scalability.
