Preparation and bioactivity evaluation of hydroxyapatite-titania/chitosan-gelatin polymeric biocomposites

Organic/Inorganic bioactive materials Part III: in vitro bioactivity of gelatin/silicocarnotite hybrids

“…For the G/S hybrids obtained after immersion process, both the FTIR spectra (Figs. 9 and 10) exhibit the presence of ν 1 -ν 4 PO 4 3-modes [10,17,18,24,58,60,61]. For the two samples the infrared absorption bands of ν 2 CO 3 2-were found at 866 cm -1 with a shoulder at 872 cm -1 for G/S 25:75 wt.% (Fig.…”

The influence of chicken scratch collagen with local hydroxyapatite as bone substitute material toward the bone remodelling of Rattus Sprague Dawley

“…Hydroxyapatite is porous and mechanically weak, which make it cannot withstand too much pressure. [11] Hydroxyapatite synthesized from gypsum with microwave hydrothermal method based on chemical reaction. [12] Collagen is a protein found in many human bodies and reaches 30% dry weight of the body.…”

Mineralization of pristine chitosan film through biomimetic process

“…3. Before immersion, the pure chitosan film showed smooth surface morphology except small undulations in the longitudinal directions [11] causing a little roughness on the film as shown in Fig. 3(a).…”

“…: +91 44 22574772; fax: +91 44 22574752. Extensive research has been undertaken to develop various polymer based composite biomaterials, among which chitosan-HA composites have attracted much attention as new bone substitute material due to the presence of HA which can accelerate the formation of bone like apatite on the surface of the implants [11]. The preparation of chitosan-HA composite by biomimetic method is a simple and viable method which gives a controlled hierarchical structures and tailor made properties [12].…”
