“…As a preliminary procedure for identifying the intactness of chitin structures in these composites we used a specific chitin stain Calcofluor White (CFW), the fluorescent brightener [26,27,[39][40][41][42][43][44][45][46]. CFW binds to the glucan chains and linear β-(1,4)-glucosidically linked units of N-acetyl-D-glucosamine.…”

range of uses. Here, chitin-based scaffolds isolated from the skeleton of marine demosponge Aplysina aerophoba were used as a template for the in vitro formation of iron oxide from a saturated iron(III) chloride solution, under hydrothermal conditions (pH~1.5, 90 °C). The resultant chitin-Fe 2 O 3 three dimensional composites, prepared for the first time via hydrothermal synthesis route, were thoroughly characterized using light, fluorescence and scanning electron microscopy; as well as with analytical methods like Raman spectroscopy, electron diffraction and HR-TEM. The results show that this versatile method allows for efficient chitin mineralization with respect to hematite. Additionally, we demonstrate that chitin nanofibers template the nucleation of uniform Fe 2 O 3 nanocrystals.

“…This, together with the "mechanical selection theory", encouraged Raabe and co-workers [98] to hypothesize that the α-chitin matrix relative to the local sample coordinates turns out to be mechanically favorable, providing maximum protection. Ehrlich et al [59] also showed that incorporation of α-chitin into proteinaceous skeletons of fresh water sponge (Spongilla lacustris) appears to be selectively favored because the resulting material becomes more rigid. Moreover, α-chitin identified within the holdfast of endemic freshwater sponge Lubomirska baicalensis plays a major role in the adhesion of sponges to rocky substrate [68].…”

Abstract:In this mini-review, we shall first cover a short history of the discovery of chitin isolated from sponges; as well as its evolutionarily ancient roots. Next, we will delve into the unique structural, mechanical, and thermal properties of this naturally occurring polymer to illuminate how its physicochemical properties may find uses in diverse areas of the material sciences. We show how the unique properties and morphology of sponge chitin renders it quite useful for the new route of "Extreme Biomimetics"; where high temperatures and pressures allow a range of interesting bioinorganic composite materials to be made. These new biomaterials have electrical, chemical, and material properties that have applications in water filtration, medicine, catalysis, and biosensing. OPEN ACCESSPolymers 2015, 7 236

“…Due to this reason, new chitin sources are being sought. Recently, some organisms such as insects, anthozoan, fungi and sponges have been researched as alternative chitin sources [13][14][15][16][17][18][19][20][21][22][23]. In the present study, the wings and other body parts of Periplaneta americana were screened for their ability to be an alternative chitin source.…”
