From: Heterogeneous distribution of dye-labelled biomineralizaiton proteins in calcite crystals

Scanning electron microscope (SEM) images of CaCO3 crystals obtained without the addition of any proteins (a) and in the presence of ~2.5 μg·mL−1 ESM-P (b) and ESM-N (c). Insets are their magnified images. ESM-P: EDTA soluble matrix from the prismatic layers of Pinctada fucata; ESM-N EDTA soluble matrix from the nacreous layers of Pinctada fucata.
