Low bone mass (osteoporosis) is a silent epidemic of the 21st century, which presently in the
UK results in over 200,000 fractures annually at a cost of over one billion pounds. Figures …

Marine sponges are able to process a variety of carbon (C), nitrogen (N), phosphorous (P),
and silicon (Si) dissolved compounds, in addition to the particulate C, N, and P obtained …

The silicified bipartite cell walls of diatoms (Bacillariophyceae) are produced in intracellular
compartments by precipitation from supersaturated Si (OH) 4 and are then externalized …

Silica deposition is a fundamental process in sponges. Most sponges in the Classes
Demospongiae and Hexactinellida secrete siliceous elements, which can subsequently …

Despite its inherent mechanical fragility, silica is widely used as a skeletal material in a great
diversity of organisms ranging from diatoms and radiolaria to sponges and higher plants. In …

Metazoans use silicon traces but rarely develop extensive silica skeletons, except for the
early-diverging lineage of sponges. The mechanisms underlying metazoan silicification …

Covering: up to 2007 Biosilicification is an evolutionarily old and widespread type of
biomineralization both in unicellular and multicellular organisms, including sponges …

The conjugation of inorganic materials with biological systems has attracted research
interest, as a consequence of the availability of the sol–gel process, operating under …

Les éponges sécrètent une variété de squelettes minéraux de calcite, d'aragonite et (ou) de
silice amorphe qui les renforcent et les protègent des perturbations physiques. La …

Sponges [Porifera] are the phylogenetically oldest metazoan phylum still extant today; they
share the closest relationship with the hypothetical common metazoan ancestor, the …
