Abstract

The invention belongs to the technical field of biomedicine application of micro total analysis systems, and particularly relates to an integrated multifunctional controllable cell control and analysis micro-fluidic chip and application of the chip. The integrated multifunctional controllable cell control and analysis micro-fluidic chip comprises an inertia focusing structure formed by continuous asymmetric bend channels, a laminar flow structure formed by a plurality of branch channels and a joining channel, a micro-fluidic control liquid drop forming structure and a micro-array capturing structure, wherein all the structures are connected through a channel, the inertia focusing structure, all branch channels of the laminar flow structure and the micro-fluidic liquid drop forming structure respectively have a solution injecting hole, and the micro-array capturing structure has a solution injecting hole and a waste solution outlet. According to the integrated multifunctional controllable cell control and analysis micro-fluidic chip, multiple functional structures are integrated in cell analysis for solving the problem that functions of high-flux analysis, trace analysis, cell controllable manipulation and the like in an existing cell analysis method are difficult to integrate, and the technical field is promoted to be further developed.
