Abstract: An exemplary embodiment of the present invention provides for a fluid ejection device. The fluid ejection device includes a substrate, a conductive layer, a resistive layer, and at least one upper layer. The conductive layer is disposed on the substrate and an outer perimeter and an inner region thinner than the outer perimeter. The outer perimeter includes conductive elements spaced apart from one another. The resistive layer includes an outer resistive portion overlying the conductive elements and a central resistive portion lying on top of a raised bridge of the substrate, wherein the width of the raised bridge is substantially greater than the width of the central resistive portion. The at least one upper layer defines a boundary of a fluid chamber, and the boundary is aligned vertically above a border of the central resistive portion.

Abstract: A sample-reagent mixture is thermal cycled through a plurality of cycles. Each thermal cycle includes actuating a heater to heat the sample-reagent mixtures; and dispensing a fluid onto the sample-reagent mixture to cool the sample reagent mixture.
