An Ultracompact Real-Time Fluorescence Loop-Mediated Isothermal Amplification (LAMP) Analyzer.

Low-cost access to the highly sensitive and specific detection of the pathogen in the field is a crucial attribute for the next generation point-of-care (POC) platforms. In this work, we developed a real-time fluorescence nucleic acid testing device with automated and scalable sample preparation capability for field malaria diagnosis. The palm-sized battery-powered analyzer equipped with a disposable microfluidic reagent compact disc described in the companion Chap. 16 which facilitates four isothermal nucleic acid tests in parallel from raw blood samples to answer. The platform has a user-friendly interface such as touchscreen LCD and smartphone data connectivity for on-site and remote healthcare delivery, respectively. The chapter mainly focuses on describing integration procedures of the real-time fluorescence LAMP analyzer and the validation of its subsystems. The device cost is significantly reduced compared to the commercial benchtop real-time machine and other existing POC platforms. As a platform technology, self-sustainable, portable, low-cost, and easy-to-use analyzer design should create a new paradigm of molecular diagnosis toward a variety of infectious diseases at the point of need.
