What is Lateral Flow Assays

Chapter 13
Advances in MEMS and Microfluidic Systems
An easy and quick diagnostic test called a lateral flow assay (lfa) is used to find out whether a target molecule is present or absent in a sample, usually a liquid like blood or urine. Lfas are based on the immunoassay theory, which use antibodies to find particular antigens.

Abstract
The unexpected increase of the global SARS-CoV-2 or COVID-19 pandemic in early 2020 has required exceptional methods to accomplish instant detection and decrease the spread rate. This chapter highlights the advance of lab-on-chip biosensing devices for the identification of COVID-19 infection. In this chapter, the authors study the roles of using lab-on-chip equipment in response to the present global COVID-19 pandemic, comprising their potential for rapid sample-to-answer processing times and facility of incorporation into a variety of healthcare backgrounds.
