A microfluidic device, including: a main body, a sealing layer and a plurality of Polymerase Chain Reaction (PCR) units arranged on the main body. Each PCR unit includes a microchannel arranged on a surface of the main body, and a sample reservoir, an oil reservoir, a droplet generation zone, a transition zone, a droplet storage zone and a collection zone that are communicated with each other through the microchannel. The sealing layer is arranged on the surface of the main body to seal the main body. After generated, the droplets are collected in the oil reservoir and then distributed to the droplet storage zone through the transition zone.
