Title:
PRINTING APPARATUS MATCHED WITH MICROFLUIDIC CHIP AND PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/236760
Kind Code:
A1
Abstract:
Disclosed herein are a printing apparatus matched with a microfluidic chip and a printing method. A printing head comprises: a printing channel configured for outputting particles and a specific liquid, and an auxiliary channel located on one or two sides of the printing channel or surrounding printing channel. When an image recognition system judges that a certain number of particles or a certain volume of liquid is output through a printing port, an auxiliary printing liquid is rapidly output through the auxiliary channel and blended with the droplets around the printing port, thus facilitating the natural drop of the droplets under the action of gravity. The present invention helps the natural drop of the liquid droplets containing the printing liquid or particles by increasing the volume of the droplets, thereby effectively avoiding the influence of conventional rapid spraying-based printing methods on the particles inside the liquid, especially on cell activity.
