ABSTRACT: In this paper, using Langmuir monolayers of dipalmitoylphosphatidylcholine (DPPC) as template, we have investigated the controlled crystallization of calcium and strontium carbonates to understand the biomineralization process at the inorganic-organic interface better. Although the calcite with a well-oriented (104) crystal plane has been obtained, as for the strontium carbonates, DPPC monolayers have resulted in the formation of the flower-like assemblies of strontianite needles; however, the oriented growth under the monolayers has not appeared. Using the lattice matching and electrostatic interaction at the inorganic-organic interface, we have discussed the possible mechanism of the phenomena.
