Estimating the term…
A microfluidic has a paper-based layer. The paper-based layer is provided with a test cell having a first contact angle region and a second contact angle region. The contact angle of a liquid in the test cell in the first contact angle region is greater than the contact angle in the second contact angle region. By the mechanism of chroma migration on a paper chip, the surface tension of the liquid is regulated and controlled, so that the liquid has a driving force pointing to the inside of the liquid drop, and thus contracts from the first contact angle region to the second contact angle region to drive the chroma to migrate to the second contact angle region to be enriched, thereby increasing the chromaticity and uniformity of a unit area while the concentrations of target objects to be tested are the same.
A microfluidic paper-based chip, comprising a paper-based layer that is provided with a test cell, which has a first contact angle region and a second contact angle region therein, and is arranged as follows:
A microfluidic test system, comprising a microfluidic paper-based chip, wherein the microfluidic paper-based chip comprises a paper-based layer that is provided with a test cell, which has a first contact angle region and a second contact angle region therein, and is arranged as follows:
A liquid test method, comprising the following steps:
