A method for observing cells, a chip and a device are provided. The method includes: (1) a camera obtaining dynamically the position of cell, the direction and speed of flow in the microchannel within the chip on stage through a microscope and transferring the data to a computer, (2) the computer collecting real-time data from the camera and analyzing it, calculating the relation between the position of cell and pressure needed in the assay, at the same time comparing the result obtained with the real-time pressure fed back by micro pressure devices and received by the computer, and inputting controlling commands to micro pressure devices; (3) based on the commands, micro pressure devices changing the pressure of two ends of microchannel in the chip to adjust the direction and speed of flow in the microchannels of chip so as to regulate the position of cell in the flow. Observing of cells can be completed quickly with accuracy according to the invention. The present invention can be applied in dynamic study for cell in scientific research, medical detection and teaching.
