Device Engineering For Infectious Disease Diagnosis Using Isothermal Dna Amplification And Lateral Flow Detection, Kristina Roskos

KGI Theses and Dissertations

Technologies that enable infectious diseases diagnosis in low-resource settings could greatly facilitate effective treatment and containment of such diseases. Nucleic acid amplification testing can be used to identify pathogens, but typically requires highly-trained personnel and large, expensive lab equipment, neither of which is available in low-resource settings. Our overall goal is to develop a portable diagnostic system that utilizes a low-cost, disposable, mesofluidic cartridge and a handheld electronics unit to perform fully-integrated nucleic acid testing at the point of care in low-resource settings. As a first step toward this goal, we developed a subunit to execute isothermal nucleic acid amplification …
