Electrochemical synthesis and optimization of poly(4-methoxyphenol) film as a sensor material

Abstract

This article describes that electrochemical polymerization of 4-methoxyphenol in the presence of enzyme glucose oxidase produces adherent polymeric films containing the active enzyme onto the surface of platinum electrodes. Polymeric electrodes prepared in this one-step procedure can be operated for the glucose determination. The effects of the electrochemical polymerization parameters (for example, concentrations of monomer, electrolyte, and enzyme; film thickness; and polymerization potential) on the electrode preparation and the effects of amperometric measurement parameters (for example, pH, temperature) on the amperometric responses to the glucose of the prepared electrodes were systematically investigated, and optimal values were determined. Furthermore, glucose specificity and storage stability of the enzyme electrode were investigated.

Synthesis, characterization of poly(4, 4’-diaminophenylethanepyromellitimide) and its use as immobilized enzyme polyimide membrane

“…9,10 Polymer-modified electrodes are widely used in the field of permselective membranes and biosensors. [11][12][13][14][15][16] Enzymes immobilized on the membrane should maintain their activity for the substrate. Several possible methods for immobilizing the enzymes, such as entrapping, formation of poly(ion complex) (PIC), and covalently bonding with the microelectrodes, have been investigated.…”
