Figure 4. Mechanical properties of HPE hydrogels was evaluated using unconfined compression test.

Figure 4

(a) Representative stress strain curves for different concentration of HPE hydrogels are shown. (b) Increase in HPE concentration resulted in an increase in compressive modulus indicating formation of highly crosslinked network. The error bars represent mean ± standard deviation (n=3), (*p < 0.05).
