Influence of Fibroin Membrane Composition and Curing Parameters on the Performance of a Biodegradable Enzymatic Biosensor Manufactured from Silicon‐free Carbon

In this work, fibroin, polylactide (PLA) and carbon are investigated for their suitability as biocompatible biodegradable materials amperometric biosensors. For purpose, screen-printed electrodes on the substrates fibroin PLA modified with a glucose oxidase membrane then encapsulated material Ecoflex. The influence of different curing parameters resulting biosensor characteristics is studied. morphology by scanning electron microscopy, performance examined measurements (0.5−10 mM) in phosphate buffer solution, pH 7.4, at an applied potential 1.2 V versus Ag/AgCl reference electrode. Instead Ecoflex, wound adhesive tested alternative encapsulation compounds: series swelling tests compositions, Ecoflex has been performed before characterizing most promising candidates chronoamperometry. Therefore, completely covered particular material. Chronoamperometric H2O2 concentrations between 0.5 10 mM enable studying leakage current behavior. This article protected copyright.
