Microfluidic paper-based analytical devices (µPADs) have gained significant attention in science and technology due to their numerous advantages over traditional techniques, including cost-effectiveness, miniaturization, sustainability. µPADs are widely used point-of-care diagnostics, health monitoring, environmental detection, food safety, forensics, security. Since the first report 2007, there been substantial advancements fabrication detection methods, applications. Over years, efforts made improve manufacturing scalability, user-friendliness, sustainability of µPADs. In this review, we explore general trends fabrication, sensing applications µPADs, highlighting key improvements innovations. We also examine eco-friendliness present real-world success stories from field studies citizen initiatives. Additionally, address challenges associated with transitioning lab field. Finally, outlook for propose strategies usefulness various fields.

Widespread concern over surface water pollution has led to interest in developing easy-to-use accurate tools for citizen-based measurements that provide high spatial and temporal resolution while maintaining accuracy. Excessive anthropogenic phosphate significantly contributes global eutrophication necessitates regular on-site monitoring waters. Traditional instrumentation quantifying is labor-intensive, expensive, performed laboratories. Existing testing methods relying on phosphomolybdenum blue (PMB) have limited sensitivity stability under ambient conditions. To overcome these limitations, a novel low-cost, rapid, user-friendly sensor citizen-led introduced demonstrated with sampling campaign. The fast-flow microfluidic device provides operation, achieving an environmentally relevant limit of detection (LoD) 190 ppb, which near the EPA-recommended maximum phosphate. dip-and-read operation reduces procedural steps delivering sample volume, making it well-suited science initiatives. This exhibits selectivity prolonged two months sensor's performance was validated using industry-standard UV–Vis method 90% correlation. More than 1000 sensors were deployed different continents, facilitating mapping diverse sources across multiple continents. initiative covered much globe, including Thailand, Nepal, Brazil, Chile, USA, Germany. In some cases, levels exceeded legislative guidelines by 100-fold. Through collaboration citizen scientists, we analyzed regional topography socioeconomic practices sources, identifying potential could contribute areas.
