Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0025] Such as figure 1 with figure 2 As shown, a two-dimensional microfluidic paper chip of the present invention includes a hydrophobic transparent film 3 and a hydrophilic paper channel 1. The pattern of the paper channel is not limited to the style in this embodiment. Other styles of hydrophilic channel and hydrophobic substrate 2 can be designed according to the needs. The hydrophilic paper channel 1 and the hydrophobic substrate 2 are detachably connected by waterproof double-sided adhesive tape. The surface of the hydrophobic transparent film 3 has a hydrophilic The inlet 4 of the liquid to be tested corresponding to the paper channel, the hydrophobic substrate 2 is a kind of glass, hy...

Abstract

The invention discloses a two-dimensional microfluidic paper chip and a preparation method thereof. The two-dimensional microfluidic paper chip, from top to bottom, sequentially comprises a hydrophobic transparent membrane, a hydrophilic paper channel and a hydrophobic substrate, wherein the hydrophilic paper channel and the hydrophobic substrate are detachably connected by a waterproof double-faced adhesive tape, the surface of the hydrophobic transparent membrane is provided with a to-be-tested liquid inlet corresponding to the hydrophilic paper channel, and the preparation method of the paper chip is also very simple and quick. The two-dimensional microfluidic paper chip disclosed by the invention adopts a simple manufacturing method and is easy to carry, and can be used for rapid field test.

Description

technical field [0001] The invention relates to the field of microfluidic chips, in particular to a two-dimensional microfluidic paper chip for detection and analysis. Background technique [0002] Paper-based microfluidics, referred to as paper chip, uses paper (such as filter paper, chromatographic paper, nitrocellulose membrane, etc.) The area between the hydrophobic and interphase forms a paper channel, and integrates basic operation units such as sampling, separation, reaction, and detection. A chip that runs through the entire system with a controllable fluid and realizes the analysis function of a conventional laboratory. Since Harvard University Martinez first proposed the concept and produced paper chips based on it in early 2007, microfluidic paper chips have been successfully used in medical diagnosis, environmental monitoring, food safety and nutrition monitoring and other fields, and research on it has also attracted more and more attention. more and more atten...
