Biomimetic HA nanocrystals were produced as described by Nocerino et al.44 (link) Briefly, HA nanocrystals were precipitated from an aqueous solution of (CH₃COO)₂Ca (75 mM) by slow addition (one drop per second) of an aqueous solution of H₃PO₄ (50 mM), keeping the pH constant at 10 (by the addition of (NH₄)OH solution). The synthesis was performed at room temperature. After this last process, the suspension of HA was washed with distilled water in order to remove ammonium ions and favor the interaction between nanocrystals.
Transmission electron microscopy (TEM) investigation was carried out using a 1200 EX microscope, linked to X-ray analysis detectors and a 3010 UHR operating at 300 kV (JEOL Ltd, Tokyo, Japan). Few droplets of the samples (in ultrapure water) were deposited on perforated carbon foils supported on conventional copper microgrids. The surface area was determined using a Sorpty 1750 instrument (Carlo Erba Reagents S.r.l., Milan, Italy) using N₂ absorption at 77 K.45

Scaffold Characterization via SEM and BET

B-HA and S-HA scaffolds were analyzed using scanning electron microscopy (SEM). Samples were washed with saline, fixed by 2.5% glutaraldehyde and with a 1% osmium solution in phosphate buffer. The specimens were coated with colloidal gold and analyzed using scanning electron microscopy (SEM, model Stereoscan S-360, Cambridge UK) [41 (link)].
The open and total porosity of the studied ceramics was measured using Archimedes’ method and geometrical weight-volume evaluation, respectively. The specific surface area (SSA) of the scaffold was measured using the nitrogen adsorption method, following the Brunauer–Emmett–Teller (BET) model (Sorpty 1750, Carlo Erba, Milan, Italy).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
