Rapid detection of viral, bacterial, fungal, and oomycete pathogens on tomato with microneedles, LAMP on a microfluidic chip, and smartphone device

Rapid detection of plant diseases before they escalate can improve disease control. Our team has developed rapid nucleic acid extraction methods with microneedles and combined these with loop-mediated amplification (LAMP) assays for pathogen detection in the field. In this work, we developed LAMP assays for early blight (
