“…Microbial biosensors are excellent alternative to conventional analytical methods because of their specificity, fast detection and low cost of analysis. Combination of microbial cells with different materials for the construction of biosensors is described in the literature [22][23][24][25][26][27][28][29][30][31].…”

Here we report the synthesis of a novel conducting polymer and its properties as an immobilization platform for biosensor application. The conducting polymer has functional groups used for the formation of amide bonding with the enzyme immobilized on the polymer surface. After covalent immobilization of glucose oxidase (GOx) on the polymeric matrix, its application for glucose biosensing was investigated in detail. Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and contact angle measurements were used to monitor the surface properties of the polymer before and after biomolecule conjugation. The optimized biosensor showed a very good linearity between 0.01 mM and 1.2 mM, a 13 s response time and a detection limit (LOD) of 0.004 mM to glucose. Also, kinetic parameters, operational and storage stabilities were determined. Apparent Michaelis constant (K m app ) and I max values of 1.17 mM and 11.28 mA, respectively, were obtained.
