Organic templates employed by nature in the biomineralization process are found to be responsible for the controlled nucleation of inorganic phases. In calcium carbonate mineralization acidic components of biomacromolecules play a vital role in controlling the nucleation. Shell cross-linked nanoparticles (SCKs) are kinetically trapped micelles, with their acidic shell region can potentially mimic these biomacromolecules. In this presentation influence of SCKs and micellar aggregates as biomimetic templates for calcium carbonate mineralization will be discussed.
