(a) SEM images of apatite-coated CH (3%), CH/CS (3% CH with 3% CS), and CH/AG (3% CH with 3% AG) scaffolds: upper panel: low magnification. Scale Bar = 100 µm; lower panel: high magnification. Scale Bar = 30 µm (b) ATR-FTIR Spectra of CH (3%), CH/CS (3% CH with 3% CS), and CH/AG (3% CH with 3% AG) scaffolds before (CH, CH/CS, CH/AG) and after (Ap-CH, Ap-CH/CS, Ap-CH/AG) apatite coating. A plate-like apatite layer was formed on the surface of scaffolds after apatite coating.
