The sea urchin-shaped CaCO3 via template mineralization on surface-functionalized vaterite particles by tiopronin-protected gold nanoparticles
The sea urchin-shaped particles of CaCO3, i.e., spherical vaterite covered with needle-shaped aragonite, were formed by template mineralization of CaCO3 in the presence of the anionic gold nanoparticles modified spherical vaterite in water.
