A hydrogen peroxide microelectrode to use in bioelectrochemical systems

- A microelectrode was developed that detects H2O2 on polarized surfaces.
- Traditional H2O2 microelectrodes failed to operate in an electrical field, while newly developed H2O2 microelectrodes operated successfully.
- Combined reference and working electrode construction minimized the effect of an electric field.
- The sensitivity of the H2O2 microelectrode was improved.
