This work presents a rotational-pulse actuated micro-fluidic cartridge enabling automated detection of plant pathogens on a compact device towards point-of-use monitoring of food safety. This highly integrated “Lab-on-a-Disc” (LoaD) system first runs the sample over a stationary phase of silica beads, followed by ethanol (EtOH) wash and final elution of DNA. The eluate is then homogenized using ‘shake mode’ agitation, accurately metered and then mixed with reagents for loop-mediated isothermal amplification (LAMP). We successfully purify plant DNA and demonstrate on-disc quantitative LAMP amplification.
