Abstract

Herein, composite electrospun nanofibers (NFs) based on polyacrylonitrile (PAN) and smectite clay, montmorillonite (Mt) were employed as matrices for the development of amperometric glucose biosensors. Clays are established as suitable immobilization platforms for biocatalysts and allow functionalization through intercalation with organic molecules. The present study was focused on utilization of functional Mt in biosensing by incorporation in nanocomposite NFs and cross-linking of model enzyme, glucose oxidase (GOx).
