The design of novel biomaterial relies on an understanding of the organicmatrices and templating structures. The aim of the present study was to investigate the compositionand the properties of skeletal structures of marine sponge (Verongula gigantea) and octocorals (Is-idella sp.) in particular by using instrumental analytical (i.e. electron transmission and scanningmicroscopic methods, vibrational spectroscopies) methods. Modern gentle demineralization tech-niques were used. It was shown, that the demosponge V. gigantea has much potential as a bioma-terial due to the multilayered structure of its rigid fibrous skeletons. The results of FTIR andRaman spectroscopy unambiguously showed that all specimens of the investigated sponge havea-chitin as the main skeletal component. Nano-crystalline aragonite was isolated and identifiedin V. gigantea, a sponge usually described as lacking a mineral skeleton. Bamboo corals of the Isid-idae family were additionally investigated. An inorganic component within the deep-sea octocoralIsidella sp. could be clearly identified as calcite by using Raman spectroscopy. The organic part wasidentified as a nanoorganized fibrillar proteinaceous matrix with acidic properties.a 2009 King Saud University. All rights reserved. |
