A micropipette system based on low driving voltage carbon nanotube actuator

We have fabricated a pipette system driven by a carbon nanotube (CNT) electroactive polymer (EAP) actuator, equipped with commercially available two- and three-way solenoid valves and experimentally estimate the suction/discharge/dropping performance for pure liquid water. The droplets were reproducibly dispensed with an RSD % of less than 2 % in their volume. The pipetting precision is within the maximum permissible error defined by the ISO 8655 standard. This work shows an example of one of the practical uses of CNT-based actuators.
