Peculiarities of Ion-Exchange Adsorption of Ca2+ and HPO 4 2 − as Main Factor of Self-Assembly of Apatite in the Surface Layer of Biomineralization Initiators

Based on analysis of the literature and the authors’ own data on the formation of apatite (the main component of bone tissue) a mechanism is proposed for its self-assembly in living organisms on the surface of various initiators of biomineralization. It consists of alternating ion-exchange adsorptio...

Summary:Based on analysis of the literature and the authors’ own data on the formation of apatite (the main component of bone tissue) a mechanism is proposed for its self-assembly in living organisms on the surface of various initiators of biomineralization. It consists of alternating ion-exchange adsorption of calcium cations and hydrogen phosphate anions accompanied by alternation of the sign of the electric charge on the surface. Experimental data from study of the adsorption cycles of Ca2+ and HPO42− ions by cation exchangers are presented in support of the proposed mechanism.
