Mechanical characterization of scaffolds: Compressive strength of the chitosan flock scaffolds (CFS), alginate hydrogels (ALG), and chitosan/alginate flock scaffolds (CFS+ALG) were measured with a 100 N load sensor in wet state. Each sample had a diameter of 15 mm. The initial load was 0.1 N, and the compression rate was 5 mm/min. Compressive strengths were defined as the stress (kPa) at 20%, 40%, and 50% compression (strain) during the second of ten loading cycles to a maximum compression of 50%. Mean ± SD, n = 3. p-value **** < 0.0001, *** 0.0001–0.001.
