The invention discloses a micro-fluidic device for instantly detecting levodopa and a preparation method and use steps of the micro-fluidic device. The micro-fluidic device is prepared by the following steps: firstly, laminating filter paper, then, placing a mold with a specific pattern and size on the filter paper, and drawing the mold on the laminated filter paper by using a hydrophobic material; and loading the water-soluble polymer and diethanol amine to the sub-region of the corresponding filter paper layer to obtain the microfluidic device. According to the method, the foldability of filter paper and the visualization of fluorescence color are utilized, and diethanol amine interacts with levodopa to generate a blue fluorescent material, so that the concentration range of the levodopa is determined. The microfluidic device provided by the invention can effectively solve the problems of long detection period, complex operation and the like of levodopa in the prior art, can effectively ...
