Hierarchically nanostructured hydroxyapatite: hydrothermal synthesis, morphology control, growth mechanism, and biological activity

Abstract: Hierarchically nanosized hydroxyapatite (HA) with flower-like structure assembled from nanosheets consisting of nanorod building blocks was successfully synthesized by using CaCl 2 , NaH 2 PO 4 , and potassium sodium tartrate via a hydrothermal method at 200°C for 24 hours. The effects of heating time and heating temperature on the products were investigated. As a chelating ligand and template molecule, the potassium sodium tartrate plays a key role in the formation of hierarchically nanostructured HA. On the … Show more

“…Hybrid membrane exposure to SBF (Supporting Information 5) gives rise to elongated needle‐like and flower‐like microparticles that form porous hollow HAp spheres, which corroborates with the morphology described for this mineral . These observations also attest to membrane bioactivity, confirming the FT‐IR and XRD analyses.…”

“…Despite the high simplicity of nanoprecipitation, a great control over morphology and size can be achieved by modification of experimental conditions [24][25][26] and the addition of surfactants [27] (e.g., stearic acid, monosaccharides and cetyltrimethylammonium bromide (CTAB)) and chelating agents [28,29] (e.g., trisodium citrate and potassium sodium tartrate). Thus, the way reactants are mixed, the solvents that are employed or the pH conditions play a fundamental role on the final structure and morphology.…”
