The Characteristics, Swelling Ratio and Water Content Percentage of Chitosan-gelatin/limestone-based Carbonate Hydroxyapatite Composite Scaffold

The tissue engineering field has developed a scaffold that can be used to increase the bone regeneration process. Carbonate hydroxyapatite (CHA) is well-known due its human bones resembling components. was synthesized from K, G, and limestone-based CHA using freeze-drying method with K-G/CHA ratios (w/w) of 40:60, 30:70, 20:80, 10:90. A Fourier transform infrared spectroscopy (FTIR), scanning electron microscope-energy dispersive X-ray (SEM-EDX), diffraction (XRD) were characterize scaffold. FTIR test showed some functional groups, such as hydroxyl, amide I, II, carbonate, phosphate. SEM-EDX micropore (<50 um) macropores (>50 structures well elements C, N, O, Mg, Al, Si, P, Ca. XRD analysis obtained crystalline amorphous particles. water content percentage (WCP) values 61.29%, 64.30%, 67.71%, 67.78%. composite ratio 30:70 ideal characteristics, swelling ratio, percentage.
