Abstract (en)
[origin: WO9942558A1] Methods of manufacture and devices for performing active biological operations utilize various structures to advantageously collect and provide charged biological materials to an array of microlocations. In one embodiment, a device includes focusing electrodes to aid in the direction and transport of materials from a collection electrode to an array. Preferably, one or more intermediate transportation electrodes are utilized, most preferably of monotonically decreasing size between the collection electrode and the array, so as to reduce current density mismatches. In another aspect, a flow cell is utilized over devices to provide containment of solution containing materials to be analyzed. In yet another embodiment, a concentric ring design is provided. Various flip-chip embodiments are disclosed.
