Abstract: The present disclosure provides a microfluidic chip and a droplet separation method, and belongs to the field of biological chip technology. The microfluidic chip includes a first liquid tank and a second liquid tank opposite to each other and a channel layer therebetween. The channel layer includes a plurality of microfluidic channels separated from each other, first ends of the microfluidic channels are communicated with the first liquid tank, and second ends are communicated with the second liquid tank. The first liquid tank contains sample solution to be detected, and the second liquid tank contains encapsulating liquid. The sample solution to be detected entering the first liquid tank may be separated into a plurality of sample droplets through the microfluidic channels, the separated sample droplets enter the second liquid tank, so that the encapsulating liquid is encapsulated on a surface of each of the plurality of sample droplets.
