Figure 3.

Mechanical strength of GelAGE versus pre-incubation time prior to crosslinking with flow chart, circle (•) represents crosslinking with designated time of pre-incubation and triangle (▼) represents the samples with further pre-incubation after replenishment of photoinitiator at t = 30 min: (a) 1 mM/5 mM Ru/SPS, (b) LAP, (c) Ig2959, (d) 1 mM/10 mM Ru/SPS and (e) 1 mM/20 mM Ru/SPS and (f) flow chart of the experiment. Values in the figures represent means and standard deviation of N = 9 replicates. Capped lines are for comparison with different groups (before and after replenishment) while straight lines are for comparison within the same group. Asterisks (*) represents values statistically significant at the p < 0.05 level, ** for p < 0.01, *** for p < 0.001 and **** for p < 0.0001. Pound (#) sign represents no-gel formation and (^) represents non-measurable. ns represents values statistically non-signigicant.
