Characterization of gelatin and chitosan scaffolds cross-linked by addition of dialdehyde starch
Abstract
In this study the influence of the addition of dialdehyde starch on the properties of scaffolds based on gelatin and chitosan obtained by the freeze-drying method was investigated. In addition, the adhesion and proliferation of human osteosarcoma SaOS-2 cells on the obtained scaffolds was examined. Chitosan and gelatin were mixed in different weight ratios (75/25, 50/50, 25/75) with 1, 2 and 5 wt% addition of dialdehyde starch. The obtained scaffolds were subjected to mechanical testing, infrared spectroscopy, swelling measurements, low-pressure porosimetry and zeta potential measurement. Internal material structures were observed by scanning electron microscopy. The results showed that the cross-linking process occurred after the addition of dialdehyde starch and resulted in increased mechanical strength, swelling properties, zeta potential and porosity of studied materials. The attachment of SaOS-2 cells to all modified materials was better compared to an unmodified control and the proliferation of these cells was markedly increased on modified scaffolds.
