PEG–Fluorescein Release Kinetic Constant from Both Types of Hydrogels under Constant or Minimal Shear Obtained from Fitting Experimental Data Using eq 4^a

	shear		nonshear
type of crosslinked hydrogel	k (min−n)	n	k (min−n)	n
radical-initiated photopolymerized PEG–norbornene hydrogel	0.0098 ± 0.0067	1.01 ± 0.22	0.0089 ± 0.0074	1.07 ± 0.44
base-initiated polymerized PEG–maleimide hydrogel	0.0005 ± 0.0006	1.64 ± 0.34	0.0012 ± 0.0018	1.56 ± 0.39

^an is the release exponent, and k is the release kinetic constant.
