“…The common trend shows that the wettability of the surfaces apparently determines the accumulation kinetics of zoospore and diatoms, even though the terminating chemistries are entirely different. The general trend confirms the Berg limit which predicts inertness for contact angles below 65° [79,80]. Furthermore, the curve shows a minimum for the settlement of Ulva and Navicula on different SAMs at a contact angle of &35°.…”

This review article summarizes some recent insights into the strategies used by marine organisms to select surfaces for colonization. While larger organisms rely on their sensory machinery to select surfaces, smaller microorganisms developed less complex but still effective ways to probe interfaces. Two examples, zoospores of algae and barnacle larvae, are discussed and both appear to have build-in test mechanisms to distinguish surfaces with different physicochemical properties. Some systematic studies on the influence of surface cues on exploration, settlement and adhesion are summarized. The intriguing notion that surface colonization resembles a parallelized surface sensing event is discussed towards its complementarity with conventional surface analytical tools. The strategy to populate only selected surfaces seems advantageous as waves, currents and storms constantly challenge adherent soft and hard fouling organism.

“…From the perspective of intrinsic wettability, these two experiments show the same result, that the unidirectional liquid-transport ability decreases with the increase of intrinsic contact angle, and they also have a similar threshold for unidirectional liquid transport, i.e., an intrinsic contact angle of 62-65°, approximately corresponding to the newly defined critical angle of 65°. [64,65] These findings are also found for other Nepenthes-inspired surfaces. [60] For example, on the peristome-mimetic surface fabricated by stereolithography, liquid ethanol and FC-72, which have intrinsic contact angles below 62-65° on a PDMS surface, show unidirectional liquid transport.…”

Surfaces Inspired by the Nepenthes Peristome for Unidirectional Liquid Transport

The slippery peristome of the pitcher plant Nepenthes has attracted much attention due to its unique function for preying on insects. Recent findings on the peristome surface of Nepenthes alata demonstrate a fast and continuous unidirectional liquid transport, which is enabled by the combination of a pinning effect at the sharp edges and a capillary rise in the wedge, deriving from the multiscale structure, which provides inspiration for designing and fabricating functional surfaces for unidirectional liquid transport. Developments in the fabrication methods of peristome‐inspired surfaces and control methods for liquid transport are summarized. Both potential applications in the fields of microfluidic devices, biomedicine, and mechanical engineering and directions for further research in the future are discussed.

“…The 658 CA is strongly related to the boundary between hydrophobic and hydrophilic, which was recently defined by surface tension measurements. [74] A certain surface roughness is necessary to obtain superhydrophilic and superhydrophobic surfaces, which can be derived theoretically from Wenzel's, [75] and Cassie-Baxter's law (Fig. 6g).…”

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.
