    • 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.

    • The invention relates to a device (102) arranged for measuring a geometry of a fluid meniscus (132). The device comprises a fluid chamber (104) storing a first electrically conductive fluid (128) and a second electrically insulating fluid (324). The fluids are mutually immiscible and define a fluid meniscus (132) in between them. Furthermore a main electrowetting electrode (118) and auxiliary electrowetting electrodes (120, 122, 124, 126) are provided for controlling the geometry of the fluid meniscus. Hereto a voltage source (134) for providing a voltage between the main electrowetting electrode and the auxiliary electrowetting electrodes is comprised, as well as a measurement circuit (144) for separately measuring capacitances between the main electrowetting electrode and at least two of the auxiliary electrowetting electrodes. For this purpose the measurement circuit comprises a multiplexer for demodulating a signal indicative for said capacitances. The invention further relates to a method for measuring a fluid meniscus.
