Abstract:
1. A microfluidic liquid dispenser assay system comprising: a target receptacle comprising a platen, the platen comprising a first planar surface, a first opening on the first planar surface, an opposing planar surface, and a second opening on the opposing planar surface, wherein the target receptacle is a through-hole; at least one transfer pin for transferring a microfluidic sample of liquid to the target receptacle, the at least one transfer pin having a slot for holding the microfluidic sample; and a pin tip at an end of the transfer pin structured to cooperate with the first opening in the target receptacle, the pin tip having a high voltage potential for transferring the sample from the at least one transfer pin to the target receptacle; and a voltage control module configured to apply the high voltage potential to the pin tip to encourage wetting of a liquid bridge between the pin tip and the through-hole; wherein the through-hole extends from the first opening on the first planar surface of the platen to the second opening on the opposing planar surface of the platen, and wherein the through-hole is submersed in a liquid that is immiscible with the microfluidic sample.
