Embodiment Construction

[0038] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0039] Glossary:

[0040] Liquid metal: liquid metal refers to an amorphous metal, which can be regarded as a mixture composed of positive ion fluid and free electron gas. Liquid metal is also a liquid metal that is flowable at room temperature.

[0041] Microfluidic chip: Microfluidic chip technology integrates 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. Due to its great potential in the fields of biology, chemistry, and medicine, it has developed into a new research field interdisciplinary in biology, chemistry, medicine, fluid, electronics, materials, and machiner...

Abstract

The invention relates to a micro fluidic chip capable of forming liquid state metal liquid drops. The micro fluidic chip capable of forming liquid state metal liquid drops comprises a substrate provided with a micro channel layer; the micro channel layer comprises a first micro channel, a second micro channel, a narrow opening, and a third micro channel; the first micro channel and the second micro channel are communicated through the narrow opening; the width of the first micro channel and the width of the second are much larger than the width of the narrow opening; the central axis of the first micro channel and the central axis of the second micro channel in the length direction are in a same straight line; the angle between the third micro channel and the first micro channel is controlled to be 30 DEG; the first micro channel, the second micro channel, and the third micro channel are respectively used for flowing of liquid state metal, generated liquid state metal drops, and a solution. The micro fluidic chip and the liquid state metal liquid drop generation method are simple and convenient in operation; the size of the generated liquid drops is convenient to control; and costis low.

Description

technical field [0001] The invention relates to the field of electrocapillary technology, in particular to a microfluidic chip capable of forming liquid metal droplets and a preparation method thereof. Background technique [0002] At present, the method of making liquid metal droplets is mainly to use a microfluidic focusing device to make droplets. This method has many advantages in producing droplets, but the production process is relatively cumbersome and the operation is more complicated. Because the prior art is mainly used to make liquid metal droplets by means of fluid shear force, this requires another kind of liquid (mostly using a mixed solution of glycerin and NaOH) that is incompatible with liquid metal and has a high viscosity. for shearing liquid metal. And two micro-flow pumps are needed to control the flow rate ratio of liquid metal and glycerol-NaOH solution, and the operation is cumbersome. Contents of the invention [0003] In view of this, the prese...
