Abstract

Multi-layer devices suitable for thermal cycling processes. The devices are particularly suitable for performing polymerase chain reactions (PCR). One embodiment includes a first conducting layer, a second conducting layer adjacent to the first layer, and a third conducting layer adjacent to the second layer opposite the first layer. Insulating layers are positioned between said three conducting layers. Continuous channels are formed within the layers. The channels can be formed in either the conducting layer or the insulating layers, or both. Other embodiments include two conducting layers. At least one integral or separate temperature source may be provided to maintain the conducting layers at various desired temperatures.
