Abstract

The invention belongs to the technical field of microfluidic droplet generation, and discloses a crisscross microchannel integrated droplet generation chip, which comprises a chip bottom plate and a chip channel integration plate, wherein the chip channel integration plate is laminated on the chip bottom plate; the chip channel integration plate is provided with a first through hole which enclosesa droplet collection and storage pool with the chip bottom plate; the chip channel integration plate is provided with a crisscross groove which forms a crisscross microchannel with the chip bottom plate; one end of the crisscross microchannel is communicated with the droplet collection and storage pool; the chip channel integration plate is provided with a second through hole, a third through hole and a fourth through hole, which enclose a first oil phase conveyance pool, a second oil phase conveyance pool and a sample phase conveyance pool with the chip bottom plate respectively; another three ends of the crisscross microchannel are communicated with the first oil phase conveyance pool, the second oil phase conveyance pool and the sample phase conveyance pool. The chip provided by the invention can be used for moving out a batch of droplets onto an application platform at one time and the breakage and the fusion of the droplets, which are caused by the multiple liquid transfer by multichannel multiple outlets, are prevented.

Description

technical field [0001] The invention relates to the technical field of microfluidic droplet generation, in particular to a cross-shaped microchannel integrated droplet generation chip. Background technique [0002] The micro-droplets generated by the microfluidic droplet generation chip have the characteristics of small volume, large specific surface area, fast speed, high flux, uniform size, closed system, and internal stability. It has important applications in the fields of catalysts and so on. The development of microfluidic chip technology provides a new platform for the controllable design and precise manipulation of size specifications, structural morphology and functional characteristics in the generation of microdroplets, which greatly strengthens the high sensitivity and low The advantages of consumption, high throughput, and automation have attracted increasing attention from various industries, and have shown great application potential in the fields of physics,...
