Abstract

The oxygen-diffusivity (D_m) of 16 different gels formed with synthetic prepolymers (photo-crosslinkable resins, urethane resins and photosensitive resins), and that of calcium alginate (for comparison) was determined, using an oxygen electrode covered by the gel membranes with stepwise enzymatic removal of O₂ from the buffer solution. The water content of the gels was found to be decisive for the O₂-diffusivity of the gels: gels with the highest water content showed also the highest D_m. From these findings, the suitability of different polymeric gels for substrate conversion and biosensor systems could be predicted.
