In example implementations, a cell trapping array is provided. The cell trapping array includes a plurality of plates coupled along adjacent edges to form a channel. A plurality of orifices are formed in a first plate of the plurality of plates of the channel. The plurality of orifices is shaped to create a meniscus of a fluid in the channel in the plurality of orifices that is to attract a single cell from cells flowing through the channel in the fluid. The cell trapping array includes a selective ejection system coupled to a second plate located opposite the first plate of the channel. The selective ejection system is to selectively eject the single cell from one of the plurality of orifices.
