After oxygen, silicon (Si) is the second most abundant element in the environment and is present as impurity in most of the materials. The widespread occurrence of siliceous biominerals as structural elements in lower plants and animals suggests that Si plays a role in the production and maintenance of connective tissue in higher organisms . It has been shown that Si is necessary in the bones, cartilage and in the formation of the connective tissue, as well as in some important metabolic processes . Additionally, well known is that Si participates as SiO2 in the precipitation of apatite layers on bio-active glasses.
