Real-time Detection of Algal Blooms (Harmful Algae)

Harmful algal blooms (HABs)—fueled by nutrient pollution and climate change—are growing threats to marine biodiversity and coastal communities. These blooms release dangerous biotoxins that disrupt food webs, endanger seafood safety, and jeopardize public health.

Screen-printed electrochemical sensors (SPEs) now provide a breakthrough solution. These compact, low-power devices enable real-time, in-situ detection of harmful algal activity—empowering rapid response and early intervention before ecological or economic damage escalates.

These sensors detect key algal biomarkers, including chlorophyll a (biomass indicator), phycotoxins (harmful bloom signals), and redox-active metabolites, providing early insights into algal activity, bloom progression, and ecosystem health.

Their high-resolution output supports predictive modeling, enabling data-driven management of HABs across aquaculture zones, fishing grounds, and recreational coastlines.

With SPE technology, coastal stakeholders gain a scalable, real-time tool to safeguard marine ecosystems, fisheries, and communities from toxic environmental threats.
