ABSTRACT:
The cell-delivery unit of a high-throughput electrophysiological testing system is implemented as a reusable movable unit suitable for repetitive delivery of cells to a disposable, multi-aperture patch-clamp tray. An electric field emanating from the patch aperture is used to align the dispenser with the aperture. A set of electrodes in the nozzle of the dispenser is used to detect the electric field and effect the alignment. According to another aspect of the invention, dielectrophoretic fields produced by sets of electrodes in the nozzle form a retaining cage that is used first to suspend a test cell directly above the patch aperture and then to urge the cell toward it. A movable cell sorter may also be coupled to the cell-delivery unit.
