Problems solved by technology

[0002] In the prior art, when liquid samples are analyzed and tested, the amount of liquid samples required is too large
Taking the detection of heavy metal ions in blood as an example, the traditional atomic absorption method requires at least 2 ml of blood, and the operation is complicated and expensive
[0003] When manipulating highly toxic and volatile liquid samples, it is easy to cause pollution due to the contact between the liquid sample and the manipulating tool

Abstract

The present application provides a method and system for manipulating the movement of tiny liquid droplets. By vibrating the liquid substrate, the liquid droplets to be manipulated are suspended in the standing wave field, and the movement of the stagnation point in the standing wave field is controlled, so as to realize the control of liquid Drop manipulation. Since the liquid sample is not in contact with the surface of the operating tool during operation, the risk of contamination of the liquid sample is reduced, and at the same time, the liquid sample is prevented from adhering to the surface of the tool to increase the consumption of the liquid sample. Because it can be operated in batches, the operation steps are simplified, the workload and liquid sample consumption are reduced, the work efficiency and precision are improved, and it is environmentally friendly.

Description

technical field [0001] The present application relates to the technical field of ultrasonic levitation, and in particular, to a method and system for manipulating the movement of tiny droplets. Background technique [0002] When analyzing and detecting a liquid sample in the prior art, the required amount of the liquid sample is too large. Taking the detection of heavy metal ions in blood as an example, the traditional atomic absorption method requires at least 2 ml of blood, and the operation is complicated and expensive. [0003] During the manipulation of highly toxic and volatile liquid samples, it is easy to cause contamination due to the contact between the liquid samples and the manipulation tools. [0004] Therefore, how to achieve non-contact manipulation of small-volume liquid samples is an urgent problem to be solved. SUMMARY OF THE INVENTION [0005] In view of the above-mentioned deficiencies of the prior art, the purpose of the present application is to pro...
