Problems solved by technology
Once the external drive device fails to operate, the microfluidic detection component will lose its function, which is very inconvenient to use
[0003] In addition, most of the current microfluidic detection components adopt a disposable design. This kind of microfluidic detection component can no longer be used after a single detection is completed, and new microfluidic detection components are frequently replaced, which will lead to fluid detection costs and detection time. A substantial increase

The invention relates to a microfluid detection unit and a fluid detection method. The microfluid detection unit includes at least one fluid injection area, a fluid storage area and a detection area. Each fluid injection area defines a fluid outlet; the fluid storage area is in gas communication with the atmosphere, and the fluid storage area defines a fluid inlet; the detection area defines a first end connected to the fluid outlet and a second end connected to the fluid inlet. A height difference is formed between the fluid outlet and the fluid inlet along the direction of gravity, so that the gravitational potential energy of the fluid outlet is greater than the gravitational potential energy of the fluid inlet. Wherein the first fluid is injected from at least one fluid injection area, so that the first fluid is guided through the detection area by gravity and converges into droplets at the fluid inlet, at this time, from the fluid outlet to the first fluid at the same height as the liquid surface of the droplets The capillary pulling force in the anti-gravity direction and the gravitational potential energy of the fluid cancel each other out to achieve a fluid pressure equilibrium state.
Description
technical field [0001] The invention relates to a microfluid detection unit, in particular to a microfluid detection unit which does not need an additional driving device to drive fluid for detection. The invention also includes a fluid detection method. Background technique [0002] In fields such as biotechnology or medicine, it is often necessary to detect fluid samples containing specific components, molecules or target analytes. The detection of the aforementioned fluid samples is mostly judged by the characteristics of the fluid and the biochemical or chemical reactions triggered. With the advancement of science and technology, microfluidic technology has gradually developed vigorously, and has been widely used in the detection of fluid samples. The application of microfluidic technology to detect fluid samples can greatly reduce the volume of fluid samples and detection equipment required. However, in order to drive fluid samples to flow in the microchannels in the ...
