Abstract: An exemplary embodiment of the present disclosure provides a system comprising a pipette tip manipulable between a sample area and an active agent exposure zone and a controller configured to manipulate the pipette tip between the sample area and the active agent exposure zone, wherein when the pipette tip comprises at least a portion of a biological sample target, the controller is further configured to isolate at least a portion of the biological sample target from one or more biological sample targets. Also disclosed is a method for detecting an effect of an active agent on a cell, by forming a high-resistance seal between a cell and an apertured surface, isolating at least a portion of the cell, translocating the apertured surface in one or more translations within an x-plane, a y-plane, a z-plane, or combinations thereof, and exposing the portion of the cell to an active agent.
