摘要
The present invention relates to an apparatus 1 for transferring cells 2 suspended in a fluid 3 from the fluid 3 to a substrate 17. The apparatus 1 comprises a transfer device 8 having an exterior surface 9, an interior cavity 10, and a plurality of passages 11 each having a first end 12 at the exterior surface 9 and a second end 13 in fluid 5 communication with the cavity 10 and each having a diameter corresponding to a predefined size of the cells 2 to be transferred. The apparatus further comprises a pressure regulating device 14 capable of regulating a pressure in the cavity 10 so as to establish a pressure difference between the first and second ends 12, 13 of each passage 11, a container 4 for containing the fluid 3, and a flow device 7 capable of causing the fluid 3 to flow across the 10 exterior surface 9 when in contact with the fluid 3. By appropriate selection of passage diameter, pressure difference and fluid flow velocity, the transfer device can be used to pick up and transfer cells 2 within a predefined size range. The invention further relates to a method for transferring cells 2 by use of such an apparatus 1.
