This I-Corps project is based on the development of a sensor to detect phosphorous levels in water. Excess phosphorus in water resources is a major contributor to harmful algal blooms and eutrophication (nutrient enrichment), which threatens ecosystems, drinking water safety, and agricultural sustainability. Current phosphorus testing methods are often expensive, slow, and unsuitable for field use. This technology uses a composite material that provides accurate and real-time detection of phosphorus compounds with strong resistance to environmental interference, making it suitable for field deployment. The technology is designed to address the growing need for portable, affordable, and reliable detection tools. The goal is to enable early and accessible phosphorus detection in lakes, rivers, and runoff sites. This sensor technology may provide a solution to critical gaps in current phosphorus detection technologies in multiple sectors, including agriculture, wastewater management, industrial discharge monitoring, municipal water utilities, and private well systems. Stakeholders in these sectors could use the technology to monitor phosphorus levels leading to enhanced public health, reduced ecological damage, and support of data-driven nutrient management practices. This I-Corps project utilizes experiential learning coupled with a first-hand investigation of the industry ecosystem to assess the translation potential of a nanocomposite material-based electrochemical phosph
