The Earth's crust is composed almost entirely of silicates, compounds of silicon (Si) and oxygen, and interacts with water on a massive scale to yield a hydrosphere replete with dissolved Si. It is biology, however, that controls the global Si cycle. Single-celled algae take up the majority of dissolved Si to construct their ornate cell walls composed of silica. Terrestrial plants require a constant supply to defend against biological and physical stresses, and, in mammals, Si is essential for stimulating connective tissue growth. Virtually nothing is known, however, about the chemical mechanisms underlying silicon biofunctionality.

地壳几乎全部由硅酸盐、硅(Si)和氧的化合物组成，并与水大规模相互作用，形成一个充满溶解硅的水圈。然而，控制全球硅循环的是生物。单细胞藻类吸收了大部分溶解的硅，形成了由二氧化硅组成的华丽的细胞壁。陆生植物需要持续的供应来抵御生物和物理压力，在哺乳动物中，硅是刺激结缔组织生长所必需的。然而，人们对硅生物功能背后的化学机制几乎一无所知。
