Design considerations for point-of-need devices based on nucleic acid amplification for COVID-19 diagnostics and beyond

Abstract

Currently, the ongoing pandemic has created an unprecedented pressure for the development of various analytical assays and especially their immediate practical applications. A number of tests based on different principles such as immunoassay [1], electrochemistry [2], nucleic acid amplification tests (NAATs) [3] and others have been reported [4]. Immunoassays and NAATs are currently being utilized clinically, while systems based on several other principles did not go further than the acceptance of manuscripts for publication.Currently, the ongoing pandemic has created an unprecedented pressure for the development of various analytical assays and especially their immediate practical applications.
