| Abstract Scope |
In this study, a new approach for bone tissue engineering is considered by using gelatin (GEL), sodium alginate (SA), hydroxyapatite (HA) and platelet rich plasma (PRP). Control group (without PRP), and containing 2% PRP, 5% PRP scaffolds were fabricated with 3D printing technology and various characterization tests were performed. The fabricated scaffolds were subjected to characterization tests that included morphological analysis using scanning electron microscopy (SEM), examination of their mechanical properties through compression test and analysis of the chemical bonds and functional groups of the scaffolds using Fourier Transform Infrared Spectroscopy (FTIR). In addition, the release test with UV spectroscopy is used to determine the amount of PRP released from the scaffold over a period of time. |
