Abstract
Methods, apparatus, and applications for use of a stacked, reconfigurable system for electrophoretic transport are provided. In one embodiment, a system having a first chamber including at least a bottom support and an intermediate support, and a second chamber, said second chamber including a bottom support and a top member, the first and second chambers being coupled through a via. Electrophoretic, and optional electro-osmotic and thermal, transport is effected. In another aspect of this invention, three or more chambers are coupled by an electrophoretic buss. The electrophoretic buss includes driving electrodes and is adapted to receive fluid containing materials for transport. The chambers are coupled to the electrophoretic buss and serve as a tap from the buss for delivery of charged materials. In one embodiment, certain functions are performed in different chambers. For example, the first chamber may receive the sample and perform sample processing functions, the second chamber may perform amplification procedures, yet a third chamber may perform hybridization or other assays, and yet another chamber may perform immunoassays. By separating various functions to different chamb…
