Abstract: Disclosed are a spheroid array and more particularly, a droplet trapping structure array capable of isolating all or selected spheroids into an isolated droplet array environment and the use thereof. The droplet-trapping structure array and the method and device for transferring spheroids using the same have the advantages of transferring droplets or spheroids with very high efficiency and very small variation between users by simply contacting two arrays. The spheroid transfer method and device enable mass-production of spheroid arrays in an isolated environment. In particular, the droplet trapping structure array and the spheroid transfer method can be useful for the treatment of spheroids with various reagents and the exchange of culture media.
