Embodiment 1

[0062] In this embodiment, the droplet generation and collection device consists of an atomization inlet, a sedimentation channel, a sedimentation pattern mask (that is, a mask with a pre-designed sedimentation pattern) and a collection interface (that is, a droplet collection interface) It consists of four parts.

[0063] Such as figure 1 As shown, the atomization generating device preferably adopts an ultrasonic atomizing sheet. In order to form a uniform and rapid droplet array, it is more appropriate to select a spray outlet aperture of about 5-9 microns. It is embedded in the bottle cap with screw cap, and the screw cap on the bottle cap is fixed and sealed with the settling channel to prevent the leakage of spray droplets. In this embodiment, the settling channel can be made of glass or plastic transparent material, so as to facilitate the observation of the aerosol settling process. The priority is to choose the common 500ml plastic bottle for modification, which is l...

Abstract

The invention belongs to the field of biological analysis and micro-manufacturing, and discloses a high-flux droplet array rapid preparation device based on spray assistance. The device sequentially comprises, from top to bottom, an aerosol droplet generation device used for atomizing a liquid to form aerosol droplets, and specifically formed by connecting an atomizer and a base; an aerosol droplet restraining and settling channel which is used for restraining the settling and diffusion area of the aerosol droplets so as to control the settling and collecting area of the droplets; and a droplet collection interface which is used for receiving droplets obtained after sedimentation and collecting to obtain a droplet array. The droplets may preferably be preserved in air for at least seven days by a temperature differential supply assembly. By improving the arrangement of all the components in the device, the corresponding matching working mode and the like, the problems of droplet arraypreparation, control and further storage can be effectively solved, and the ultra-fast forming device is an ultra-fast forming device for the ultra-high-flux droplet array assisted by spraying.

Description

technical field [0001] The invention belongs to the fields of biological analysis and micromanufacturing, and more specifically relates to a spray-assisted rapid preparation device for high-throughput droplet arrays. Using the device, rapid preparation of high-throughput droplet arrays can be realized, and hundreds of The ultra-low-cost generation of thousands of droplets, and at the same time, the selective preparation of space-controllable droplets can be realized through the mask, which can be stored in the air for more than ten days, providing a high-throughput droplet microenvironment. A new approach that can be widely used in miniaturized high-throughput applications such as microbial cultivation and screening, nanoparticle fabrication and assembly, sensor fabrication, and biochemical detection. Background technique [0002] In recent decades, the concepts of miniaturization and high-throughput quantification have developed rapidly in the field of biological and chemic...
