“…Each layer is composed of parallel fibers of probable chitin-protein chemical nature along which are aligned nanogranules, as previously observed for other analyzed crayfish gastroliths such as Orconectes limosus and Cherax quadricarinatus (Luquet et al, 2013(Luquet et al, , 2016Shechter et al, 2008a;Travis et al, 1960Travis et al, , 1963. A similar organization was also described by Habraken et al (2015) for gastroliths of a crayfish, the genus and species of which are not named in the study, so that detailed comparisons are not possible.…”

“…4). Elemental distribution seems heterogeneous for most of them, more particularly for Mg and P. Two layers appear particularly enriched in Mg. P exhibits a layered distribution with an alternate richness from the beginning of the storage until the middle of the gastrolith, corresponding to the first and second regions of the gastrolith as described by Travis (1963). Then, a relatively homogeneous distribution is observed until the end of the storage (convex side).…”

International audienceDuring premolt, crayfish develop deposits of calcium ions, called gastroliths, in their stomach wall. The stored calcium is used for the calcification of parts of the skeleton regularly renewed for allowing growth. Structural and molecular analyses of gastroliths have been primarily performed on three crayfish species, Orconectes virilis, Procambarus clarkii, and more recently, Cherax quadricarinatus. We have performed high-resolution analyses of gastroliths from the native noble crayfish, Astacus astacus, focusing on the microstructure, the mineralogical and elemental composition and distribution in a comparative perspective. Field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM) observations showed a classical layered microstructure composed of 200-nm diameter granules aligned along fibers. These granules are themselves composed of agglomerated nanogranules of 50 nm-mean diameters. Denser regions of bigger fused granules are also present. Micro-Raman spectroscopy show that if A. astacus gastroliths, similarly to the other analyzed gastroliths, are mainly composed of amorphous calcium carbonate (ACC), they are also rich in amorphous calcium phosphate (ACP). The presence of a carotenoid pigment is also observed in A. astacus gastrolith contrary to C. quadricarinatus. Energy-dispersive X-ray spectroscopy (EDX) analyses demonstrate the presence of minor elements such as Mg, Sr, Si and P. The distribution of this last element is particularly heterogeneous. X-ray absorption near edge structure spectroscopy (XANES) reveals an alternation of layers more or less rich in phosphorus evidenced in the mineral phase as well as in the organic matrix in different molecular forms. Putative functions of the different P-comprising molecules are discussed

Bio-inspired synthesis of polymer–inorganic nanocomposite materials in mild aqueous systems

It is increasingly important that we learn how to fabricate materials in environmentally friendly ways using common resources that are abundant in nature. Biomineralization, the process by which living organisms create a variety of sophisticated composites, such as bone and shell, is an ideal model for such fabrication. This article reviews recent progress toward the synthesis of polymer-inorganic composite materials inspired by biomineralization. In particular, three reaction systems are focused upon: (1) polymer-calcium carbonate thin film composites synthesized by interaction among insoluble polymer, soluble acidic polymer, and inorganic ions, (2) polymer nanogel-calcium phosphate composite nanoparticles synthesized on scaffolds of hydrogel nanoparticles and (3) colloidal silica nanoparticles made to self-assemble into anisotropic chain-like structures by interaction with block copolymers. All these reaction systems involve aqueous environments at ambient temperature and pressure.
