Schematic design of the experimental setup for Single Particle Tracking: a 3-axis piezo-stage mounted on a commercial confocal microscope (Zeiss LSM510-Confocor3) is used to move the sample with respect to the focal spot. The movement of the piezo-stage along the 3 axis is controlled by a PC through a card that generates the input voltages. The same card is used for acquisition of the signals from the detection unit of the microscope. The position of the piezo-scanner can be monitored connecting the capacitive sensors outputs to an oscilloscope.
