摘要
A method of controlling a needle actuator to interact with a cell is provided, the method comprising: providing an actuator comprising a tower, a stage and a needle, wherein the needle is mounted on the stage; applying an electrostatic potential between the tower and the stage to retract the needle; moving the actuator towards the cell; reducing the potential so as to allow the stage and needle to move towards the cell; applying calibration data to detect when the needle has pierced the cell; and reducing the potential further once it has been detected that the needle has pierced the cell. The cell can be a biological cell. The needle can be a micro-needle and the stage can be a micro-stage.
