Over the past decade, researchers have been exploring the potential of microfluidic systems as a platform for diagnostic devices due to their ability to reduce reagent consumption and costs compared to conventional laboratory systems. While initial promise was seen in this technology, limitations such as the size, complexity, and cost of pumps or pressure control systems required to accurately move small volumes of fluids hindered its full realization. However, recent advancements in paper-based diagnostics have provided an exciting opportunity to overcome these challenges.
