Rheological investigation of copolymer aqueous solutions. A Gelation temperatures of PLGA-PEG and 0.5 IU/µL EPO-PLGA-PEG were 30.4 and 30.9 °C, respectively (n = 3/group). B Tan(δ) was less than 1, indicating solid-like behavior for PLGA-PEG and EPO-PLGA-PEG in the physiologic temperature range (n = 3/group). C Solution to gel (sol-gel) transition of EPO-PLGA-PEG occurred in 16.3 s. Plateau of the moduli over time after gelation indicated the persistence of solid-like behavior (n = 3/group). D Sol-gel transition of EPO-PLGA-PEG was fully reversible and occurred in 4398 s (n = 3/group)
