摘要：

The structure of a composite of regenerated silk fibroin (RSF) and poly(vinyl alcohol) (PVA) is characterized with FT-IR spectra. PVA has little influence upon the structure of RSF in the composite since it exhibits the same structure as those of pure RSF. The water absorption property and maximum strength of the composite are dependent upon its component. An amperometric glucose sensor using tetrathiafulvalene as an electron transfer mediator was constructed to test the feasibility and workability of the composite of RSF and PVA as an immobilization matrix of glucose oxidase. The effects of scan speed, pH, and temperature on the electrocatalytic oxidation of glucose at the sensor are discussed. The enhanced hydrophilicity of the membrane results in fast response of the sensor to glucose (less than 40 seconds). Moreover, the sensor is useable for more than 2 months.
