Abstract
A method of forming a biosensor is provided in accordance with the present invention. The method includes providing a metallized electrode support substrate and a sensor support, ablating the electrode support substrate to form electrodes, coupling the sensor support substrate to the electrode support substrate, and positioning spaced-apart electrically conductive tracks across the sensor support substrate so that each track is in electrical communication with one electrode.
Claims25
A method of forming a biosensor comprising:
- providing an electrode support substrate and a sensor support substrate having a first surface, an opposite second surface facing the electrode support substrate, and notches extending between the first and second surfaces,
- ablating the electrode support substrate to form electrodes,
- coupling the sensor support substrate to the electrode support substrate to form a capillary channel between the sensor and electrode support substrates and to align each notch with at least a portion of one electrode, wherein at least a portion of the electrodes are positioned in the capillary channel, and
- positioning electrically conductive tracks on the first surface of the sensor support substrate, a portion of each track extending from the first surface into at least one notch and being in electrical communication with one of the electrodes.
A method of forming a biosensor comprising:
- providing a metallized electrode support substrate being formed to define an electrode array and leads extending from the array,
- coupling a sensor support substrate to the electrode support substrate, the sensor support substrate being formed to include notches and an opening, at least a portion of each notch being aligned with one lead and the opening being spaced-apart from the leads, and
- positioning electrically conductive tracks on the sensor support substrate, each track extending across one of the notches and into engagement with one lead.
