Harmful algal blooms (HABs) occur when algae grow rapidly due to a combination of warm water temperatures, high nutrient levels such as phosphorus and nitrogen, and sunlight. HABs contain toxins that can foul coastlines, kill fish, and pose health risk to humans. Algal blooms also present a major problem for many desalination plants. This project uses novel low-cost on-chip sensing devices for continuous water monitoring enabling early warning of algal blooms.
