Lightwater

Lightwater Sensors has developed a photonic-based technology for real-time monitoring of water pollutants. Their solution uses optical chemical sensor materials integrated with low-cost portable instrumentation platforms. The sensors employ light-emitting polymers that lose their light emission when in contact with target molecules, allowing for selective detection of specific pollutants.

The technology offers several advantages over traditional water quality monitoring methods. It provides continuous, real-time detection instead of relying on infrequent grab-sampling and laboratory analysis. The sensor platforms are lightweight, portable, and can be easily deployed in various settings. Multiple units can be integrated into a buoy to form a multianalyte network for long-term monitoring of water bodies, drinking water intake points, and ecologically sensitive areas.

Lightwater's devices are designed to be user-friendly and cost-effective. The hardware platforms are one-time purchases with a long operational life, while the selective sensor element is a disposable, replaceable film. This approach makes the technology more accessible and practical for widespread use.

The sensors can detect a range of pollutants, including chemicals, pesticides, pharmaceuticals, and explosives. This capability makes them valuable for addressing various water quality challenges, from monitoring drinking water supplies to detecting industrial pollution and potential security threats. Overall, Lightwater's technology aims to provide a more efficient and effective solution for maintaining water quality in the face of growing global concerns about water pollution and scarcity.
