Electrostatically Sealed Paper-Based Microfluidic Device for Environmentally Robust Nitrite Determination by Griess Colorimetry

Microfluidic paper-based analytical devices (µPADs) are promising for point-of-care testing, yet most operate in an open-format that is susceptible to solvent evaporation and reagent contamination, causing poor signal stability under changing environments. Here, we present an equipment-free sealing...
