英文摘要 | Microfluidic based digital PCR (dPCR) enables precise, highly sensitive absolute quantification for nucleic acids without the need for standard curves [1]. For example, by segregating single DNA molecules in individual water-in-oil emulsion droplets, emulsion PCR (ePCR) offers the advantage of massively parallel clonal amplification of DNA templates, which allows the identification and quantization of rare mutant gene within a large population [2, 3] and enables new generation of ultra-high throughput DNA sequencing technologies [4]. More recently, microfluidic microdroplet technology has been exploited to perform PCR in droplets because of its unique features. It can prevent crossover contamination and PCR inhibition, is suitable for single-cell and single-molecule analyses, and has the potential for system integration and automation. Although significant advances have been made in developing droplet-based microfluidic PCR devices, most of them were still cannot integrate droplet formation, PCR amplification, and fluorescent signal detection into one machine. An ideal microfluidic system with implemented on-chip PCR function should be fully autonomous, easy for non-experts to use, and has complete protocol integration. In this paper, we developed a high throughput technology enabling formation and encapsulating PCR sample into solid alginate bead, locating the beads into individual chambers, which allow the on-chip PCR amplification and fluorescent imaging. We demonstrate an integrated and automatic digital PCR system, making it a promising platform for many single copy genetic studies. This platform will also greatly improve our understanding of disease pathophysiology and diagnosis. |
