From Micro To Macro: Physicochemical Surface Properties Of Biogenic Silica Structures And Their Role In Silicon Cycling

Silicon (Si) is the seventh most abundant element in the universe, and thus it can be found almost everywhere on Earth. That is why it is not surprising that numerous organisms are evolutionarily adapted to use monomeric silicic acid (H4SiO4) for the synthesis of hydrated amorphous silica (SiO2·nH2O) in a process called biosilicification. Well-known examples of amorphous silica structures are the shells of diatoms, the so-called frustules. Another less known example is the shells of the unicellular testate amoebae. Numerous...
