Digital quantification of DNA via isothermal amplification on a self-driven microfluidic chip featuring hydrophilic film-coated polydimethylsiloxane
Abstract(#br)Loop-mediated isothermal amplification (LAMP) is a DNA amplification approach characterized by high sensitivity and specificity. In “digital LAMP”, small quantities of both template DNA and reagents are encapsulated within a droplet or microwell, allowing for analysis of precious nucleic acid samples in shorter amounts of time relative to traditional DNA amplification protocols (e.g., PCR) with an improved limit of detection. In this study, an integrated, self-driven microfluidic chip was designed to carry out digital LAMP.
