| Advances in Research on Siliceous Sponge Spicules: Novel Insight into the Understanding of Biomineralization Mechanisms and Bionic Applications |
| Siliceous sponges are the simplest and oldest multi-cellular animals on the Earth. They achieved a perfect technical blueprint during their million years of evolution. A new energy-saving and environmentally friendly technology has been developed by nature for human applications allowing the production of novel bio-inorganic mineral materials using nano-biotechnological approaches. There is a wide application prospect in the fields of optical fibers, microelectronics, biomedical materials and some further areas. Monorhaphis chuni lives in the deep sea over 1000 m in depth. Its giant basal spicule is growing to a length of 3 m and is therefore the largest bio-silica structure on the Earth. It is a highly suitable model for the study of bio-silicification mechanisms and for their bionic applications. In this paper, the authors systematically summarize the research progress in these giant basal spicules on the following topics: structure, composition, mechanical properties, optophysical properties, biochemical properties and molecular biological basis, biomineralization mechanism as well as bionic applications in biomedicine. |
