Abstract
The new types of phenoxy-carboxylatophenoxy cosubstituted polyphosphazene were synthesized with various substitution rates. Diabetic diagnostic membranes were prepapared with these types of polyphosphazenes and final absorbances at 680 nm through these membranes were measured at various concentrations of glucose in blood. Basically, the end-point results of varying absorbance values according to time (K/S) had a linear relationship to the glucose concentration. The effects of substitution rates with hydrophilic carboxylatophenoxy groups and hydrophobic phenoxy groups on the glucose concentration measurements were examined. It was very difficult to measure glucose concentration in less than 10% of the hydrophilic substitution rates, because the glucose penetration rate was too slow. But dose-response slope (DRS) values between glucose concentration and K/S values increased as the hydrophilic substitution rates increased in more than 10% of the hydrophilic substitution rates. However, in more than 30% of the hydrophilic substitution rates, DRS value was too rapidly increased, because glucose penetration rate was too fast.
