Biomimetic Hydroxyapatite Crystallization in Gelatin Nanoparticles Synthesized Using a Miniemulsion Process

“…Amphiphilic block copolymer P(B/E-b-EO) (M w of the B-E block 3700 gÁmol À1 and of the EO block 3600 gÁmol À1 ) was synthesized [45,46] and used as emulsifier. p-xylene, synthetic grade from Merck, CaCl 2 Á2H 2 O from Aldrich, Na 2 HPO 4 Á2H 2 O from Merck, glutardialdehyde (50% solution in water) for synthesis from Merck, 0.01 M NaOH (Merck), resorcinol (98%) from Aldrich, and Ca 10 (OH) 2 (PO 4 ) 6 from Aldrich were used.…”

“…Interesting studies describing collagen/HAP mineralization mechanism in bone formation and synthesis of bone like HAP/collagen nanocomposite have already been reported. [3,4] Several routes have been proposed to produce nano-HAP: wet-chemistry techniques such as direct precipitation in aqueous solutions, [5,6] electrochemical depositions, [7] sol-gel procedures, [8] and hydrothermal synthesis. [9,10] The resulting suspensions, however, could only be used as surface coatings or as bulk materials after drying or by fine-spraying of HAP powders of different morphologies.…”

Effect of hydrazine deproteination on bone mineral phase: A critical view

“…The other phosphates studied were hydroxyapatite (HA), synthesized according to the method described by Lopez-Macipe et al [30], CaHPO 4 (Labsynth) and CaCO 3 (J.T. Baker) (composed mainly of calcite with aragonite traces (JCPDF-ICDD)).…”

Surface properties of various powdered hydroxyapatites

“…Samples III and IV were commercial samples from Centro de Biomateriales, Universidad de La Habana (Apafill). Samples V and VI were synthesized in the Instituto de Ciencias de Materiales de CSIC, Barcelona, Spain [30] by procedures described previously [31]. The main characteristics of the employed materials are indicated in Table 1.…”
