Quantification of the final concentration of YRGDS in swollen PEGDA hydrogels with varying macromer molecular weights as a function of (A) exposure time, (B) light intensity, (C) PEGDA concentration and (D) eosin Y concentration. Unless noted, hydrogels were formed using a PEGDA concentration of 25% (w/v) and were polymerized for one minute at 100 mW/cm2 with an eosin Y concentration of 0.05 mM. All hydrogels contained a fixed precursor YRGDS concentration of 5 mg/mL (n = 3; * = p < 0.05 and # = p < 0.001).
