Using Hydroxyapatite From Fish Scales To Prepare Chitosan/Gelatin/Hydroxyapatite Membrane: Exploring Potential For Bone Tissue Engineering, Yi-Cheng Huang, Hao-Wen Chu
Journal of Marine Science and Technology
Concerns have recently been raised about the treatment and use of hydroxyapatite, an important component of fish scale. The goal of this investigation is to evaluate the feasibility of using hydroxyapatite extracted from fish scale (FHAP) for bone tissue engineering. FHAP or sintered FHAP (sFHAP) was added to chitosan/gelatin (CS/GEL) mixture to prepare membrane. The effect of FHAP and sFHAP on the physical and chemical properties of the membrane and their affinities towards MG63 cells were studied. Accordingly, the prepared CS/GEL/FHAP membrane was characterized by FTIR (ATRFTIR) and SEM. Following sintering at 800°C for 4 h, the CS/GEL/sFHAP membrane had …

Chitosans with various degrees of deacetylation (DD) were prepared from red shrimp (Solenocera prominentis). DD of chitosan was determined by infrared spectrum. The effect of urea on the conformation and chain flexibility of chitosan molecules with various DD was studied. The results show: 1) The intrinsic viscosities of chitosan solutions containing 4 M urea were higher than those without urea addition. It indicated the chitosan molecules in solutions containing urea have higher hydrodynamic volume than that without urea. It may due to urea increasing the intramolecular hydrogen bond formation. 2) The persistence lengths of chitosan molecules were longer in solutions …
