Abstract:

A new method of micro-chemical reaction was proposed on the basis of the digitalization of micro-fluids technology, which brings a small controllable pulse inertial force to the micro-nozzle. By using this method, the micro-fluids could be digitally transported and injected as a string of micro-drops, and then the micro-chemical reaction proceeded in the mixed domain by collision and polymerization. During the micro-chemical reaction, one micro-droplet could be injected with one driving pulse. The droplets not only could be injected continuously, but also could be injected according to the codes , therefore the micro-chemical reaction could be controlled effectively. The speed and time of the micro-chemical reaction were adjusted by changing the diameter of micro-pipette and driving frequency. By using the precision glass fabrication technology, the micro-reactor had neither inner moving parts nor embedded microcircuit. It had simple structure, low cost, smooth circular cross-section glass channel and could be driven easily. The synthesis experiment of metal porphyrin was made, and the result showed that the micro-reactor could reduce reaction time and reaction temperature was lower than conventional reaction.
