Characteristics of the materials used. (a) Tangent Young’s modulus of material combinations used. Measured tangent Young’s modulus between 0 and 20% strain calculated in 5% steps for multiple material combinations (n = 4; *p < 0.05). (b) Water loss as a ratio of the original weight after compression. Lower concentrations of fibrin show significantly higher water losses. The addition of collagen reduces the water lost after compression (n = 4). (c) Contact angle measurements for thrombin, fibrinogen and gelatine solution on PEEK and gelatine surface materials (n = 6; *p < 0.05).
