Abstract: A process that includes simultaneous and/or sequential steps for separating, extracting and/or isolating all or part of the components contained in the inner aragonitic organo-mineral layer and in the outer calcitic organo-mineral layer of the shells of marine bivalve molluscs. Also, compositions including these components, such as cosmetics and medicinal products.

Abstract: A pulverulent semisynthetic material, derived from a natural marine biomaterial, namely the aragonitic inner layer of the shell of bivalve molluscs selected from Pinctadines, notably Pinctada maxima, margaritifera, and Tridacnes, notably Tridacna gigas, maxima, derasa, tevaroa, squamosa, crocea, Hippopus hippopus, Hippopus porcelanus, in pulverulent form, with the addition of insoluble and soluble biopolymers and calcium carbonate transformed by carbonation.

Abstract: A semi-synthetic hybrid material having a pH from 7 to 7.4 includes an inorganic fraction and a cross-linked organic fraction. The method for producing this material, and osteosynthesis devices or implants made of semi-synthetic hybrid material are also described.
