Abstract

The wetting kinetics and mechanism of phase interaction between hydroxyapatite (HA) and biological media (blood plasma and physiological solutions) of the human body are studied in relation to composition and porosity. It is established that the in-teraction of HA with blood plasma depends on its porosity and correlation of cohesion and adhesion between protein molecules and HA surface. The interaction of HA with physiological solutions depends on the porosity of the solid phase and composition of Ringer-Locke and Ringer-Tirode solutions. The main factors of phase interaction in HA–biological medium systems are determined: porosity of the solid phase, chemical composition and viscosity of biological media.
