Abstract

The invention provides a micro-fluid chip and a biology detection device and method, and relates to the field of biology detection. The micro-fluid chip comprises a first substrate, a second substrate, a first electrode, a second electrode, a first dielectric layer, a second dielectric layer, a first hydrophobic layer and a second hydrophobic layer, wherein the first substrate and the second substrate are opposite, the first electrode and the second electrode are opposite between the first substrate and the second substrate, the first electrode comprises multiple spaced first electrode units,the second electrode comprises multiple spaced second electrode units, each first electrode unit is opposite to the corresponding second electrode unit, the first dielectric layer and the second dielectric layer are located between the first electrode and the second electrode, the first hydrophobic layer and the second hydrophobic layer are located between the first dielectric layer and the seconddielectric layer, and a gap is formed between the first hydrophobic layer and the second hydrophobic layer. Compared with the prior art, driving voltage applied to the micro-fluid chip can be lower,and therefore, the risk that the chip is broken down can be reduced.

Description

technical field [0001] The present disclosure relates to the field of biological detection, in particular to a microfluidic chip, a biological detection device and a method. Background technique [0002] Microfluidic chip technology can integrate the basic operation units such as sample preparation, reaction, separation, and detection in the process of biological, chemical, and medical analysis into a micron-scale chip to automatically complete the entire analysis process. Because microfluidic chips can reduce costs, and have the advantages of short detection time and high sensitivity, they have shown great prospects in the fields of biology, chemistry, and medicine. [0003] In recent years, digital microfluidic technology based on dielectric wetting technology can manipulate discrete droplets, which has the advantages of less reagent consumption, cost savings, no cross-contamination, independent manipulation of droplets, and easy integration of portable systems. , has bec...
