The embodiment of the invention discloses a micro-fluidic
chip, a preparation method of the micro-fluidic
chip and a test method based on the micro-fluidic
chip. The chip comprises an injection layer, a
porous membrane layer and an
organoid culture layer which are sequentially stacked, the injection layer is provided with a first flow channel, a first inlet and a first outlet which are communicated with the first flow channel, and an introduction port; the
porous membrane layer is provided with an injection hole and a connecting port, and the connecting port is communicated with the introduction port; the second inlet, the second outlet and the
organoid culture chamber are respectively communicated with the second flow channel, the
organoid culture chamber is communicated with the injection hole, and the second inlet is communicated with the connecting port; the first inlet is used for providing a tumor
drug and an ATP nano sensor for the organoid culture chamber through the first flow channel and the injection hole; the introduction port is used for providing
tumor cells for in-vitro culture of the organoids for the organoid culture chamber through the connection port, the second inlet and the second flow channel. According to the micro-fluidic chip disclosed by the embodiment of the invention, the whole PDO-based
drug reaction test process can be executed in a single micro-fluidic chip, and the ATP in cells can be identified under the condition that the cells are not damaged through the injected ATP nano sensor.
