Abstract
The present invention discloses a droplet digital PCR chip. The droplet digital PCR chip includes at least one chip unit, each chip unit includes a chip body formed by bonding a top piece and a bottom piece, the chip body is internally provided with an inlet chamber, a droplet storage chamber, and an injection hole. The injection hole connects with the inlet chamber, a plurality of droplet generating channels are disposed between the inlet chamber and the droplet storage chamber, a height of the droplet generating channel is smaller than a height of the droplet storage chamber, an injection fluid is injected into the inlet chamber through the injection hole, and the injection fluid is emulsified and enters the droplet storage chamber at a junction of the droplet generating channels and the droplet storage chamber.
