DROPLET MICROFLUIDIC CHIP AND MICRODROPLET PREPARATION METHOD

摘要

Disclosed are a droplet microfluidic chip and a microdroplet preparation method, the droplet microfluidic chip comprises at least one droplet preparation unit, and the droplet preparation unit comprises a dispersed phase cavity, a fixed quantity cavity, a capillary nozzle, and a continuous phase cavity; the droplet microfluidic chip has a center of rotation, the dispersed phase cavity has a sample addition hole used for adding a dispersed phase fluid, the fixed quantity cavity is in communication with the dispersed phase cavity and is further away from the center of rotation than the dispersed phase cavity; the capillary nozzle is further away from the center of rotation than the fixed quantity cavity, one end of the capillary nozzle is in communication with the fixed quantity cavity and same extends from the communicating end in a direction away from the center of rotation; the continuous phase cavity is in communication with the end of the capillary nozzle away from the fixed quantity cavity and is further away from the center of rotation than the capillary nozzle, and the continuous phase cavity accommodates a continuous phase fluid.
