Claim:
1. A fluidic device comprising: an article comprising a top outer surface a bottom outer surface, a thickness, a first microfluidic channel segment formed in the top outer surface of the article, and a second microfluidic channel segment formed in the bottom outer surface of the article; an intervening channel passing through the thickness of the article thereby connecting the first microfluidic channel segment formed in the top outer surface of the article and the second microfluidic channel segment formed in the bottom outer surface of the article; a first fluid reagent stored in at least a portion of the first microfluidic channel segment, the second microfluidic channel segment, or the intervening channel; a second fluid reagent stored in at least a portion of the first microfluidic channel segment, the second microfluidic channel segment, or the intervening channel; a fluid plug positioned between, and immiscible with, the first and second fluid reagents, wherein the fluid plug contains a gas; an inlet in fluid communication with the first and second microfluidic channel segments; an outlet in fluid communication with the first and second microfluidic channel segments; a fluid-tight seal covering the inlet; and a fluid-tight seal covering the outlet.
