Abstract: A pneumatic driving device and the associated method for micro fluids, wherein the pneumatic driving device for micro fluids is constructed by connecting a fluid pipe with a structure that is formed by two gas stream inlets, a gas stream fender, a gas stream flow path and a gas stream outlet. The suction, exclusion and stagnation for the micro fluids inside the fluid pipes can be accomplished by adjusting the flow rates of the gas streams into the device at the two gas stream inlets. In the invention, several pneumatic driving devices are connected to form a single recursive pneumatic driving device by the concept of recursion, and the micro fluids inside several fluid pipes can be controlled to mix or to separate through the recursive pneumatic driving device by adjusting the flow rates of the gas streams into the device at different gas stream inlets.

Abstract: Within each of a microfluidic mixer apparatus and a microfluidic reactor apparatus, as well as respective methods for operation thereof, there is provided a substrate having formed therein an aperture. Within the microfluidic mixer apparatus and its method of operation there is introduced into the aperture at least a pair of reagents through a pair of channels which terminate obliquely at the aperture, such as to provide a swirling mixing of the pair of reagents. Within the microfluidic reactor apparatus, the aperture comprises a first end portion contiguous with a middle portion in turn contiguous with a second end portion, where the middle portion, but not the first end portion or the second end portion, has at least one baffle intruding therein.
