The adhesional properties of contaminating particles of scales of various lengths were investigated for a wide range of micro- and nanostructured insect wing cuticles. The contaminating particles consisted of artificial hydrophilic (silica) and spherical hydrophobic (C18) particles, and natural pollen grains. Insect wing cuticle architectures with an open micro-/nanostructure framework demonstrated topographies for minimising solid–solid and solid–liquid contact areas. Such structuring of the… 

Contaminant adhesion (aerial/ground biofouling) on the skin of a gecko

The lizard scales which exhibited a three-tier hierarchical architecture demonstrated higher adhesion than the trough regions between scales, and the gecko skin architecture on both the dorsal and trough regions demonstrates an optimized topography for minimizing solid–solid and solid–liquid particle contact area.

Influence of Cuticle Nanostructuring on the Wetting Behaviour/States on Cicada Wings

The nanoscale protrusions of different morphologies on wing surfaces of four cicada species were examined under an environmental scanning electron microscope (ESEM) and adhesive forces in combination with the Cassie-Baxter and Wenzel approximations were used to predict wetting states of the insect wing cuticles.

Biomimetics for early stage biofouling prevention: templates from insect cuticles.

Interestingly the most disordered replicated surface (dragonfly wing replicate) demonstrated the lowest values of absorption, and it is probable that the low adsorption properties, at least in the early stages, may be related to air trapped at the surface.

Diversity of Cuticular Micro- and Nanostructures on Insects: Properties, Functions, and Potential Applications.

Of particular importance are structures that imbue cuticle with antiwetting properties, self-cleaning abilities, antireflection, enhanced color, adhesion, and antimicrobial and specific cell-attachment properties.

Molecular and Topographical Organization: Influence on Cicada Wing Wettability and Bactericidal Properties

The data presented not only correlates the nanopillar molecular organization to macroscale functional properties, but it also presents design guidelines to consider during the replication of natural nanostructures onto engineered substrates to induce desired properties.

Journal of Nanoscience with Advanced Technology The Insect (cicada) Wing Membrane Micro/Nano Structure - Nature's Templates for Control of Optics, Wetting, Adhesion, Contamination, Bacteria and Eukaryotic Cells

The functions and functional efficiency of the insect cuticle are highlighted by focusing on the cicada wing, as an exemplary example, illustrating features that are of particular relevance for biomimetic purposes.

Microscopic modulation of mechanical properties in transparent insect wings

We report on the measurement of local friction and adhesion of transparent insect wings using an atomic force microscope cantilever down to nanometre length scales. We observe that the wing-surface

Insect Analogue to the Lotus Leaf: A Planthopper Wing Membrane Incorporating a Low-Adhesion, Nonwetting, Superhydrophobic, Bactericidal, and Biocompatible Surface.

This study shows that the planthopper insect wing exhibits a remarkable architectural similarity to the lotus leaf surface, and its cuticle provides a "new" natural surface with which numerous interfacial properties can be explored for a range of comparative studies with both natural and man-made materials.



The role of micro/nano channel structuring in repelling water on cuticle arrays of the lacewing.

Putative functions and functional efficiency of ordered cuticular nanoarrays on insect wings.

Measurements of contact angles for several liquids and particle adhesion studies show that the wing represents a low-surface-energy membrane with antiwetting properties, and the inference is that a combination of chemistry and structure constitutes a natural technology for conferring resistance to contamination.

Wetting, adhesion and friction of superhydrophobic and hydrophilic leaves and fabricated micro/nanopatterned surfaces

Superhydrophobic surfaces have considerable technological potential for various applications due to their extreme water-repellent properties. When two hydrophilic bodies are brought into contact, any

Wetting and self-cleaning properties of artificial superhydrophobic surfaces.

The wetting and the self-cleaning properties (the latter is often called the "Lotus-Effect") of three types of superhydrophobic surfaces have been investigated: silicon wafer specimens with different

In this paper, Silicon surfaces patterned with pillars and deposited with a hydrophobic coating were studied to demonstrate how the effects of pitch value, droplet size and impact velocity influence the transition from a composite state to a wetted state.

Putative function ( s ) and functional efficiency of ordered cuticular nano-arrays on insect wings

The putative function(s) and functional efficiencies of periodic nano-structures on the surface of cicada wings have been investigated by atomic force microscopy (AFM) used as a tool for imaging,

How micro/nanoarchitecture facilitates anti-wetting: an elegant hierarchical design on the termite wing.

The sophisticated micro/nanostructured hierarchy on the termite wing membrane not only results in non-wetting at different length scales but also demonstrates a design for weight and material minimization while achieving this state.

The Wetting of Insect Cuticles by Water

The observed variations of surface properties can be explained without assuming any variation in the chemical composition of the cuticle surface, which is broadly correlated with surface roughness and with habitat.
