A review.The electro-osmosis style pump of the Nano Fusion Corporation has small size (10 mm or less), high pressure, low driving voltage, no pulsation, no noise, low cost and simple structure, and also possesses unique features as that of conventional micro-pump.This pump allows stable flow of variety of liquids with the help of a particular technique, and acts as a palm size compact pumping system that can control micro flow [nL/min-mL/min] with a combination of indirect drive and flow sensor.These techniques can be considered for realization of miniaturized and accurate control of fluid systems in applications in many areas such as biol., medicine, chem. or mech. engineering.
