Microfluidic system and method of moving the analysis of liquid in the capillary passage

摘要

The present invention relates to microfluidic systems and methods for moving the fluid analysis in the capillary microchannel. The field of microfluidics, the invention relates to microfluidic systems. The plug-like body of ferrofluid (5) and (7), placed in contact with at least one of the two ends of the plug-like body of the ferrofluid, the method analyzes and ferrofluids equipped with a plug-like body of liquid immiscible with both the liquid and (7), the steps of introducing into (1) the capillary microchannel, ferrofluid single column (3) at least; near the ferrofluid column , and the side having the plug-like body of liquid immiscible with both the analytical solution and a ferromagnetic fluid (7), the steps of introducing the analysis liquid (9) in the capillary channel; which is disposed outside the capillary channel The magnetic field generated by the magnetic system has, by the action of a ferrofluid on a column, and a step of controlling the movement of the analytical solution of the capillary channel.
