Paper has been used as a platform for biological and chemical applications for over a century. Paper-based microfluidic devices have been gaining popularity over the past several years for the many advantages they provide, most notably their low cost, portability, ease of use and disposability. Paper-based microfluidic devices are made up of different sections that serve different purposes. The simpler devices generally have a sample port, into which the sample fluid is loaded, transport channels, that connect the different sections of the device, reaction zones, at which the sample fluid reacts or mixes with dry or wet reagents, and a detection zone, at which a signal is formed that can be either qualitative in nature or can be measured quantitatively. While a large number of applications have been described and implemented using paper-based microfluidic devices, opportunities for improving their performance still exist due to various advancements in the field of paper-based microfluidics. An example is the performance of a paper-based microfluidic device for the detection of nitrate. A new user friendly and inexpensive paper-based microfluidic device for the detection of nitrate was developed with improvements in the limit of detection and quantification over 40% than what has been previously published.
