Silacidins:Highly Acidic Phosphopeptides from Diatom Shells Assist in Silica Precipitation In Vitro

摘要

Biomineralization is the formation of inorganic materials under the control of a living cell.Silica biomineralization occurs,for example,in unicellular diatoms with cell walls composed of silica.Although amorphous,diatom silica displays intricate structures of amazing beauty even on the nanometer scale.
