Abstract
Controlled growth of calcium carbonate crystals with complex forms was achieved using dextran as a crystal growth modifier beneath a dipalmitoylphosphatidylcholine (DPPC) monolayer, and calcite-core-calcium bilirubinate (CaBR)-side multiple crystals were also observed owing to the epitaxial growth of CaBR crystals on calcite. During the process, interactions between the DPPC monolayer and calcium ions were studied based on the analysis of the surface pressure−molecular area isotherms. Control over the crystallization of calcite with novel morphologies, such as octahedral crystals and round calcite disks, has been observed. Remarkable morphological changes and continuous structural evolution of calcite from rhombohedral crystal to octahedral crystal to uniform round disks and polyhedrons as concentrations of dextran increased have been observed. Moreover, semirigid multiplex templates consisting of calcium carbonate crystals and DPPC monolayers were established under physiological pH conditions, and epitax...
