Figure. S3 (A) stress-strain curves of CS, CS/HAp, CS/SF, and CS-SF/HAp scaffolds.

The insert shows the stress-strain curves of the four scaffolds with strain ranging

between 0 and 0.1; (B) histograms of the elastic modulus and compressive modulus at

strain of 0.7 of CS, CS/HAp, CS/SF, and CS-SF/HAp scaffolds.
