Lattice images of individual crystals are consistent with a well-ordered magnetite cubic inverse spinel structure. The idealized morphology of the biogenic crystals is based on an elongated cubo-octahedral form comprising a hexagonal prism of {111} and {100} faces capped by (1̄1̄1) and (111̄) faces with associated {111} and {100} truncations. Analysis of many particles of diverse size suggests that crystal growth takes place in two stages. The first stage is associated with the formation of well-ordered, isotropic, single-domain crystals of cubo-octahedral morphology. In this stage the crystal length and width develop concurrently up to a size of 20 nm. The second stage involves the anisotropic growth of the isotropic particles along the [112̄] direction. A crystal growth mechanism is postulated which involves the specific nucleation of the (1̄1̄1) face on a surrounding organic membrane. Unidirectional growth then occurs by selective suppression of certain crystallographic axes through spatial and chemical constraints induced by the adjacent organic boundary.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380869864956215170","@type":"Researcher","foaf:name":[{"@value":"Stephen Mann"}]},{"@id":"https://cir.nii.ac.jp/crid/1380869864956215169","@type":"Researcher","foaf:name":[{"@value":"N.
