The development of electrochemical biosensors has been an important area of biotechnology in recent times , , , . Much of the work is devoted to the development of sensors for the determination of glucose , , , . Today, most authors consider an increase in the sensitivity and high selectivity of the working electrodes of biosensors for glucose, the ability to analyse in a wide range of concentrations, and a low working potential to be an important goal. The solution to such problems is often associated with the introduction of expensive materials such as graphene and carbon nanotubes, which increase the conductivity of the electrode material , , . Then the surface is modified by the enzyme glucose oxidase, which is an active, highly stable, well studied and commercially available oxidoreductase , . When using it, the principle of electrochemical detection of hydrogen peroxide as a product of the enzymatic transformation of the analyte (glucose) works.
