Abstract:
A laminated device for performing active biological operations on a sample comprising:a first planar sample support including at least one sample through hole, the sample through hole having a first lateral dimension, the sample through hole being adapted to receive a sample support material,a planar electrode adjacent the first planar sample support, including an electrode through region,a second planar support including a vent through hole, the vent through hole having a lateral dimension,characterized in that the planar electrode is in laminated relationship between the first planar sample support and the second planar support and in that the sample through hole, electrode through hole and vent through hole are in overlapping arrangement, the vent hole includes a lateral width defined by the shortest lateral dimension of the vent hole, and the sample through hole including a lateral width defined by the shortest lateral dimension of the sample through hole, and wherein the lateral width of the sample through hole is different from the lateral width of the vent through hole.
