A new procedure for developing high performance enzyme electrode is described. The procedure is based on the covalently binding of horseradish peroxidase to a self-assembling monolayer on a gold electrode. An enhanced catalytic current is observed with addition of hydro-gen peroxide into phosphate buffer solution (PBS) in the presence of mediators. The electrode exhibits high sensitivity and a wide linear range to hydrogen peroxide.
- High performance enzyme electrode,
- High sensitivity,
- Wide linear range
