“…Recently, our work has focused on the application of beetles as inspiration for materials science, with an emphasis on surface properties of beetle shells [45,46]. As one example, in a prior study we investigated the surface properties of G. orientalis Moser [47] and observed variations in surface wettability depending on the local coloration (white vs. black).…”

Chitosan is a polymer obtained by deacetylation of chitin, and chitin is one of the major components of the arthropod cuticle. Chitin and chitosan are both polysaccharides and are considered to be an interesting class of biosourced materials. This is evident as chitosan has already demonstrated utility in various applications in both industrial and biomedical domains. In the present work, we study the possibility to extract chitin and prepare chitosan from the Goliath beetle Goliathus orientalis Moser. The presented work includes description of this process and observation of the macroscopic and microscopic variations that occur in the specimen during the treatment. The prepared chitosan is characterized and compared with commercially available chitosan using infrared and thermogravimetric analysis. The deacetylation degree of prepared chitosan is also evaluated and compared with commercially available shrimp chitosan.

“…Closer examination revealed that the tomentose (i.e., dense hair covered) portion of the female elytra was covered in disorganized nanoscale needle-like structures separated in bunches by cracks across the surface. Meanwhile, the male elytra were found to be covered with uniform, vertically aligned, microscale and nanoscale needle-like structures [ 61 ]. Recently, a research team in Australia observed an unidentified beetle (most likely family Hydrophilidae) that was capable of walking upside-down on the underside of the water’s surface without penetrating the surface.…”

Insects demonstrate a wide diversity of microscopic cuticular and extra-cuticular features. These features often produce multifunctional surfaces which are greatly desired in engineering and material science fields. Among these functionalities, hydrophobicity is of particular interest and has gained recent attention as it often results in other properties such as self-cleaning, anti-biofouling, and anti-corrosion. We reviewed the historical and contemporary scientific literature to create an extensive review of known hydrophobic and superhydrophobic structures in insects. We found that numerous insects across at least fourteen taxonomic orders possess a wide variety of cuticular surface chemicals and physical structures that promote hydrophobicity. We discuss a few bioinspired design examples of how insects have already inspired new technologies. Moving forward, the use of a bioinspiration framework will help us gain insight into how and why these systems work in nature. Undoubtedly, our fundamental understanding of the physical and chemical principles that result in functional insect surfaces will continue to facilitate the design and production of novel materials.

“…[29][30][31][32][33][34][35][36] Since 2017, we have studied beetles both as a source of bioinspiration for surface design and more importantly as a potential source of materials such as chitin and chitosan. [37][38][39] Our interests lie in the possibility of valorising chitosan from beetles. Our first work in this area investigated the potential of large beetles (specifically, Mecynorhina torquata Drury, 1782 and Goliathus orientalis Moser, 1909) as a source of chitosan.…”
