The dependence of initial polymerization rates on GOX concentrations for (○) 1.0 × 10−3 M, (■) 5.0 × 10−4 M and (▲) 2.5 × 10−4 M of glucose. These reactions exhibit a near square root dependence of the polymerization rate on the enzyme concentration (i.e., 0.42 ±0.04, 0.45 ±0.04, 0.41 ±0.04 for 1.0 × 10−3 M, 5.0 × 10−4 M and 2.5 × 10−4 M of glucose, respectively) until a saturation point is achieved at, and above, 6.25 × 10−7 M of GOX. All reactions were performed with ambient oxygen and temperature with 2.0 × 10−4 M Fe+2, 10mM MES pH=4.5, 20wt% HEA and 15wt% PEGDA575.
