Formation and structure of zinc-substituted calcium hydroxyapatite

Selective laser sintering fabrication of nano-hydroxyapatite/poly-ε-caprolactone scaffolds for bone tissue engineering applications

“…Miyaji et al 41 reported the application of HA in blood purification due to its selective adsorption. Fujii et al 42 proposed that HA could be used to isolate viral proteins.…”

Comparative Efficacy of Experimental Solutions in Occluding Dentin Tubules: Calcium Phosphate Based and Oxalate-Based Solutions

“…Meanwhile, the Ca 2+ , Zn 2+ , F -, HPO 4 2-ions from the CaP solution would migrate into the vacancies created by ions loss in dentinal HA lattice, and then incorporate into an precipitated apatitic layer that had lower CO 3 2-ion concentration and higher F-ion concentration, which ultimately attributed to lower solubility and better acid resistance. Furthermore, this ion exchange process in combined with mechanical boding would provide the CaP precipitates more resistant to physical abrasión [30,[32][33][34][35]. In addition, CaP solution possessed antibacterial activity since F-and Zn 2+ ions can reduce the metabolism rate of oral bacteria [36], inhibit bacterial growth and colonization [37].…”

Multifunctional and hybrid systems based on calcium-phosphate and hydroxyapatite for preventive and regenerative medicine

“…Parametar kristalne rešetke c, [41] opada sa porastom sadržaja cinka, dok se parameter a povećava za koncentracije cinka iznad 5 mol%. Povećanje vrednosti parametra a pri većim koncentracijama cinka pripisano je supstituciji OH -jona molekula vode.…”
