A portable system for economical nucleic acid amplification testing

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Introduction: Regular and rapid large-scale screening for pathogens is crucial for controlling pandemics like Coronavirus Disease 2019 (COVID-19). In this study, we present the development of a digital point-of-care testing (POCT) system utilizing microfluidic paper-based analytical devices (μPADs) for the detection of SARS-CoV-2 gene fragments.

Ratiometric Fluorescence Coding for Multiplex Nucleic Acid Amplification Testing [PDF]

open access: yesAnalytical Chemistry, 2018
Although nucleic acid amplification testing (NAAT) has become the cornerstone for molecular diagnosis of diseases, expanding the multiplexed detection capacity of NAAT remains an important objective. To this end, encoding each nucleic acid target with a specific fluorescently labeled probe has been the most mature approach for multiplexed detection ...
