Amorphous calcium carbonate (ACC) is the amorphous and least stable polymorph of calcium carbonate. ACC is extremely unstable under normal conditions and is found naturally in taxa as wide-ranging as sea urchins, corals, mollusks, and foraminifera. It is usually found as a monohydrate, holding the chemical formula CaCO₃·H₂O; however, it can also exist in a dehydrated state, CaCO₃. ACC has been known to science for over 100 years when a non-diffraction pattern of calcium carbonate was discovered by Sturcke Herman, exhibiting its poorly-ordered nature.
Tooth fluoridating and remineralizing compositions and methods, based on nanoaggregate formation
ActiveUS20080292565A1Well formedAvoid repairsCosmetic preparationsToilet preparationsNano compositesWhitening Agents
Compositions and methods for forming, in an aqueous environment, a nanoaggregate of calcium fluoride and amorphous calcium phosphate-containing compound, such as amorphous calcium phosphate fluoride or amorphous calcium carbonate phosphate fluoride are described. The nanoaggregate (or nanocomposite) can release calcium, phosphate, and fluoride, and ultimately convert to the tooth mineral, fluorapatite. One method for forming such a nanoaggregate involves applying a non-aqueous (e.g., varnish-based) composition (e.g., a suspension), containing solid particles of water soluble salts of calcium, phosphate, and fluoride, to the aqueous environment of the mouth. This results in rapid solubilization of the salts, precipitation of the nanoaggregate, and tooth remineralization. Tooth fluoridation and remineralization may also be carried out by applying to the tooth a non-aqueous carrier containing the nanoaggregate. Whitening agents can also be added to these compositions and methods.

Calcium carbonate microstructures useful in encapsulation applications and a process for the preparation thereof
InactiveUS20110223111A1Useful applicationUltrasonic/sonic/infrasonic diagnosticsPowder deliveryFluorescenceAntibacterial activity
A facile method to synthesize stable calcium carbonate microstructures is demonstrated which allows in situ encapsulation of sensitive molecules like drugs. The methodology involves a macromolecular assembly of anionic polypeptide with cationic peptide oligomer to concurrently template and hold to stabilize the mineralized structure. The heterogeneously distributed mixture of anionic and cationic residues in the macromolecular assembly, similar to that is found in natural systems assists in recognizing and coassembling Ca2+ and CO32− ionic clusters, especially for formation of a disordered precursor phase such as amorphous calcium carbonate (ACC) and further crystallization to form a metastable vaterite phase. The assembly also facilitates encapsulation of a guest molecule such as tetracycline at ambient conditions without affecting the mineralization process. The tetracycline-loaded microstructures show excellent antibacterial activities against many Gram-positive and Gram-negative bacterial strains and hence together with the fluorescence property of tetracycline and appropriate drug release profile, they can be used as multifunctional materials for therapeutic and imaging applications.
