View of the microcontact printer. The LOC substrate (microscope slide) is placed in the substrate holder, which has three degrees of freedom (two translations along the Y and Z axis and one rotation θX around the X axis) for alignment. The PDMS stamp is positioned in the stamp holder, which has two degrees of freedom (two rotations θY and θZ, respectively around the Y and Z axis) to make the stamp parallel to the substrate. The stamp is guided towards the substrate by a linear slide, actuated with a pneumatic jack. The stamp is released from the substrate by reversing the direction of air flow in the piston.
