(a) Schematic representation of DNA-framework-templated crystallization of hydroxyapatite that involves DNA stabilization by calcium ions, formation of amorphous calcium phosphate due to local supersaturation, and further aging and crystallization of nanohydroxyapatite. (b) Transmission electron microscopy images showing the triangular DNA origami-hydroxyapatite nanocomposites with triangular morphology. Interestingly, the triangle tips center the crystallization trend. Reprinted with permission from ref (311). Copyright 2020 Elsevier.
