Effects of the formulation factors on PEGMC hydrogel curing time. 3D graphs of curing time (in seconds) with varying concentrations of PEGMC and PEGDA, in terms of the actual factor TEMED (represented as ‘C’), at 15 μl/ ml. Three different MWs of PEGDA, i.e., (A) 3.3 kDa, (B) 6 kDa, (C) 8 kDa, were used. Correlation factors were obtained as R2 = 0.9988, 0.8766 and 0.7665 for PEGDA 3K, 6 kDa and 8 kDa, respectively. Correlation factors were analyzed using square root transformation and either linear or 2FI fit models.
