Lateral flow assays (LFAs) have become a vital tool in various industries, ranging from medical diagnostics to environmental monitoring. These assays offer a quick and cost-effective way to detect the presence of a target substance, such as a specific biomolecule or pathogen, in a sample. In recent years, the term “microfluidic” has gained prominence in scientific discussions. But what exactly is a microfluidic lateral flow assay, and how does it differ from traditional LFAs? In this article, we will delve into the world of microfluidic technology and explore its implications for lateral flow assays.
Lateral flow assays have been a game-changer in various industries due to their simplicity, rapidity, and user-friendliness. These assays are commonly used for detecting the presence or absence of a target analyte in a sample without the need for specialized equipment or extensive training. But in recent years, a new dimension has been added to the world of lateral flow assays: microfluidic technology.
Understanding Lateral Flow Assays
Lateral flow assays, often referred to as immunochromatographic assays, rely on capillary action to transport liquid samples along a porous medium, where interactions between the target analyte and specific antibodies result in a visible signal. They have been widely employed for pregnancy tests, glucose monitoring, and the detection of various pathogens.
