Figure 1.
Swelling behavior of hydrogels with methacrylate end groups fabricated with different concentrations of APS/TEMED initiator system (10–20 mM) and 10-30 min fabrication intervals at 37°C. Hydrogels were swollen in double distilled water for 24h. Data are reported as mean ± standard deviation for a sample size of n=3–4. Asterisk denotes statistical significance between groups from the same fabrication interval (p<0.05).
