A Self-Priming Microfluidic Chip with Cushion Chambers for Easy Digital PCR

Blog Article

A polydimethylsiloxane (PDMS)-based self-priming microfluidic chip with cushion chambers is presented in this study for robust and easy-operation digital polymerase chain reaction (dPCR).The chip has only one inlet and can partition samples autonomously through negative pressure, provided by a de-gassed PDMS layer Reusable Cleaning Cloths with a multi-level vertical branching microchannel design.Meanwhile, cushion chambers make the chip capable of very robust use for sample partitioning.

Finally, the proposed microfluidic chip showed excellent performance in the absolute quantification of a target gene by performing quantitative detection of a 10-fold serial dilution DNA template.Owing to its characteristics of easy operation, low cost, and high robustness, the proposed dPCR chip is expected to further promote Footballs the extensive application of digital PCR, especially in resource-limited settings.
