NerOcean Limited

Company

NerOcean Limited is a Hong Kong-based marine technology company founded in August 2021 by scientists from City University of Hong Kong and The Education University of Hong Kong. The company's vision is to "make clean water measurable, accessible, and achievable."

The company develops three core products: a replaceable photo-sensing film dissolved oxygen sensor that reduces maintenance costs by 90%; a next-generation artificial mussel sampling device for continuous monitoring of heavy metals and radionuclides, reducing monitoring costs by 95%, deployed in over 50 countries globally; and Smart Sponge for high-selectivity oil filtration in oil/water mixtures.

Technology

NerOcean’s Artificial Mussels (AM) are smart, passive sampling devices designed for long-term monitoring of heavy metals and radionuclides in freshwater, marine water, and wastewater. Each AM unit is a compact hydrogel-based kit containing a specially synthesised chelating complex enclosed in artificial seawater within a small tube sealed by semi‑permeable gel ends, allowing dissolved contaminants to diffuse in and be accumulated over time. Deployed typically for 2-8 weeks, AMs integrate pollutant levels over time, providing more representative data than snapshot water samples while requiring no power, maintenance, or active operation.
