Chemistry and Pharmacology
The structure, water absorbability and mechanical properties of the blend membranes of regenerated silk fibroin and poly(vinyl alcohol) were investigated. IR spectra showed regenerated silk fibroin in the blend membranes exists chiefly in the silk I structure after ethanol treatment. An amperometric biosensor for glucose was constructed by coupling glucose oxidase in the blend membrane of regenerated silk fibroin and PVA with platinum electrode. Its experimental parameters such as pH, temperature and applied potential were optimized. It determined glucose in less than 25 s with good reproducibility and exhibited high storage and operational stability.
