Microfluidic chip digital PCR technology and its clinical application / 中华检验医学杂志

ABSTRACT

Microfluidics-based digital PCR depends on microfluidic chip to split PCR reaction mixture into many tiny equal-volume units.Quantitative assessment of target DNA template can be obtained by counting the number of fluorescence-positive units after thermocycling.Microfluidics-based digital PCR exhibits many advantages including absolute quantification, high sensitivity and accuracy, and shows great promise in a variety of applications, such as infectious diseases diagnose, early cancer detection and prenatal diagnose. There are already several microfludics-based digital PCR products produced from sereval companies.It is believed that as the technology improves, microfluidics-based digital PCR will find broader applications and become the next-generation tool for genetic tests.
