Abstract: A device for generating a droplet array, which comprises a substrate, a roller on the substrate, and a microgrooved chip on the outer surface of the roller, wherein a sealant is on a surface of the substrate close to the roller and the microgrooved chip comprises a chip body fitted to the roller and an array of microgrooves arranged on the chip body, the array of microgrooves consisting of a plurality of microgrooves arranged at intervals on the chip body. When the roller rolls, liquid between the substrate and the roller enters the microgrooves and forms droplets while the microgrooved chip detaches from the roller and combines with the sealant which seals the microgrooves, generating a droplet array. The device generates a droplet array having uniform droplet size, good repeatability. Further, the method is simple and highly efficient, and has broad application prospects in the fields of medicine and biology.
