PCR (polymerase chain reaction) is a molecular biological technology for amplification and amplification of specific DNA fragments. Digital PCR is the third generation PCR technology, which is an absolute quantitative technology of nucleic acid molecules. Compared with traditional qPCR technology, digital PCR(dPCR) has the following characteristics: absolute quantitative, no standard, low sample demand, high sensitivity, high tolerance and so on. At present, digital PCR technology has been widely used in pathogen detection, cancer biomarker research and copy number variation analysis, gene expression analysis, environmental monitoring, food detection and other fields.

There are two common digital PCR(dPCR) techniques: microdroplet dPCR(ddPCR) and chip dPCR(cdPCR). The basic principle of the two is the same. Due to the high cost of chip dPCR manufacturing, microdrop dPCR is more and more recognized by enterprises with lower cost and more practical advantages. Microdrop dPCR(ddPCR) has also greatly promoted the screening of suspected COVID-19 patients in the epidemic prevention and control.
