Dynamic Behavior of Glucose-Responsive Poly(methacrylic acid-g-ethylene glycol) Hydrogels
Abstract
Glucose-sensitive poly(methacrylic acid- g -ethylene glycol) (P(MAA- g -EG)) gels were synthesized by copolymerizing methacrylic acid and poly(ethylene glycol) monomethacrylate in the presence of activated glucose oxidase. The dynamic and equilibrium swelling behavior of the gels was examined as a function of pH. At low pH values the gels were in a collapsed state due to complexation between carboxyl and etheric groups. At high pH values, the gels swelled to approximately 20 times their dry weights. The glucose oxidase containing gels exhibited a higher rate of expansion than the non glucose oxidase containing gels as the former had fewer entanglements. Relaxation times were determined for the swelling and deswelling processes, and a time-dependent swelling behavior was obtained for partial swellings in different pH values.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
