Abstract
A test strip or biosensor comprising a base substrate on which an electrode system is formed. One or more laminate layers overlie the base substrate to form a sample-receiving chamber in which a reagent is deposited. An opening is provided from the sample-receiving chamber to the exterior of the biosensor. The layers and the base substrate are laser welded to secure the biosensor. One of the layer and base substrate is light transmissive to allow laser welding at the interface therebetween. The biosensor may be formed from a series of continuous webs that are subsequently sliced to form individual biosensors.
