Abstract
Microchip devices are provided which include a substrate having a plurality of reservoirs containing a secondary device, a reacting component, or a combination thereof. At least one barrier layer covers each reservoir to isolate the reservoir contents from one or more environmental components outside the reservoirs. The barrier layer can be selectively disintegrated or permeabilized to expose the isolated contents to the one or more environmental components. The secondary device preferably includes a sensor or sensing component, for example, a biosensor, or a light detection or imaging device, such as an optical fiber. Preferred reacting components include catalysts and reagent, which may be immobilized in the reservoirs.
