“…At low pH the DNA adopts an i-motif conformation (state I) which gives way to a duplex structure (state II) when the pH is raised and the complementary strand is present. Lowering the pH reverses the process and converts state II back to state I. Reproduced from [55].…”

In this review a strategy for the design of bioinspired, smart, multiscale interfacial (BSMI) materials is presented and put into context with recent progress in the field of BSMI materials spanning natural to artificial to reversibly stimuli‐sensitive interfaces. BSMI materials that respond to single/dual/multiple external stimuli, e.g., light, pH, electrical fields, and so on, can switch reversibly between two entirely opposite properties. This article utilizes hydrophobicity and hydrophilicity as an example to demonstrate the feasibility of the design strategy, which may also be extended to other properties, for example, conductor/insulator, p‐type/n‐type semiconductor, or ferromagnetism/anti‐ferromagnetism, for the design of other BSMI materials in the future.

“…Krupenkin et al (2007) reported that droplet behaviour can be reversibly switched between the superhydrophobic Cassie state and the hydrophilic Wenzel state by the application of electrical voltage and current (electrowetting). Wang et al (2007) created a surface that can switch between stable superhydrophilic, metastable superhydrophobic and stable superhydrophobic states. Interestingly, their reversible surface was driven by DNA nanodevices.…”

Biological surfaces (plant leaves, lizard and insect attachment pads, fish scales, etc.) have remarkable properties due to their hierarchical structure. This structure is a consequence of the hierarchical organization of biological tissues. The hierarchical organization of the surfaces allows plants and creatures to adapt to energy dissipation and transition mechanisms with various characteristic scale lengths. At the same time, an addition of a micro-/nanoscale hierarchical level, for example of surface roughness, can change qualitatively the properties of a system and introduce multiple equilibriums, instability and dissipation. Thus, small roughness has a large effect. In particular, a small change of surface roughness can lead to a large change in the capillary force. The capillary effects are crucial for small-scale applications. Multiscale organization of the biomimetic surfaces and their adaptation to capillary effects make them suitable for applications using new principles of energy transition (e.g. capillary engines) and environment-friendly technologies (e.g. self-cleaning oleophobic surfaces).

“…Following this principle, interfacial materials with extreme wetting states, such as superhydrophobic, superhydrophilic, superoleophobic, and superoleophilic states, can be fabricated from metals, polymers, ceramics, semiconductors, insulator, and so on. By combining micro/nanostructured substrates and responsive molecules, we can also fabricate smart interfacial materials possessing two complementary properties of superwettability that can be switched using light [22][23][24][25], pH [26][27][28][29][30][31], electric, chemical, or multi-stimuli [32][33][34]. If the design principle is transferred from an air environment to water or other liquid media, underwater superoleophobic and superareophobic surfaces can be developed [35][36][37][38][39][40][41][42].…”

Binary cooperative complementary materials, consisting of two components with entirely opposite physiochemical properties at the nanoscale, are presented as a novel principle for the design and construct of functional materials. By summarizing recent achievement in materials science, it can be found that the cooperative interaction distance between the pair of complementary property must be comparable with the scale of related physical or chemical parameter. When the binary components are in the cooperative distance, the cooperation between these building blocks becomes dominant and endows the macroscopic materials with unique properties and advanced functionalities that cannot be achieved by either of building blocks.
