Abstract
Methods of manufacture and devices for performing active biological operations utilize laminated structures. In the preferred embodiment, a first planar sample support includes at least one sample through hole, a planar electrode is disposed adjacent the first planar sample support, and includes an electrode through region, a second planar support includes a vent through hole, the planar electrode being in a laminated relationship between the first planar sample support and the second planar support, further characterized in that the sample through hole, electrode through hole and vent through hole are in overlapping arrangement. Preferably, some or all of the through holes, through regions and vent through holes are aligned. In one embodiment, the lateral dimension of the vent through hole is larger than the lateral dimension of the electrode through hole. In an alternative embodiment, the lateral dimension of the sample through hole is larger than the lateral dimension of the vent through hole.
