Abstract
A method of preparing a working electrode on a sensor substrate is disclosed. A sensor substrate is provided and has a first side with at least one conductive trace. A layer of sensing material is applied onto the first side and covers at least a portion of the at least one conductive trace. The sensing material is irradiated with a laser beam to partially remove the layer of the sensing material while preserving a portion of the sensing material covering the at least one conductive trace, resulting in a working electrode on the sensor substrate. A membrane layer is applied that at least partially covers the working electrode. The membrane layer includes a cross-linker that cross-links at least a part of the sensing material. A diffusion step is performed during which the cross-linker in the membrane layer at least partially diffuses into the sensing material.
