Abstract

original image

Filling the gaps: Unique 3D ordered macroporous (3DOM) calcite single crystals with controlled orientation and well-defined nanopatterns are fabricated by introducing amorphous CaCO3 into a colloidal crystal template of polymer spheres (see picture). Such a bioinspired strategy suggests a route to functional single-crystalline materials and sheds light on biomineralization mechanisms.
