Clean water is essential for aquatic ecosystems and the industries depending on them. Nitrogen Sensing Solutions (NS2), a pioneering Portuguese startup, has developed a portable system that measures nitrogen levels in real-time. This cutting-edge technology delivers accurate data directly to smartphones, tablets, and dashboards, eliminating the need for lab tests. 

With support from the BlueInvest programme, NS2 secured €100,000 in venture capital funding, boosting their innovative efforts.

 

Why nitrogen levels matter

Maintaining optimal nitrogen levels, especially in aquaculture and agriculture, is challenging. Excess nitrogen compounds, such as ammonia, nitrites and nitrates, can harm aquatic life and disrupt production.

Recognising the importance of this issue, Nitrogen Sensing Solutions is transforming how we monitor and manage water quality. It is bringing advanced biosensor technology into the hands of fish farmers, environmental agencies, and water managers.

 

From research to impact

Founded in 2019 by biochemistry researcher Dr. Gabriela Almeida, NS2 is based on over 20 years of scientific research in electrochemical biosensors. Motivated by the urgent need for smarter monitoring tools, Dr. Almeida put together a multidisciplinary team to turn research into practical tools for better water management. 

 

Smart monitoring 

NS2’s breakthrough technology uses small, disposable test strips and portable readers to detect ammonium, nitrites and nitrate levels in water. These biosensors offer real-time data, enabling users to make quick, informed decisions to protect aquatic life and optimise operations.

Unlike traditional methods that often rely on slow lab results, NS2’s system allows for preventive action. For fish farmers, this means preventing toxic build-ups that can lead to costly losses. For environmental agencies, it means better monitoring of water bodies and faster response to pollution. 

 

BlueInvest in action

NS2’s journey was accelerated by the BlueInvest Readiness Assistance Programme, which paired them with a coach skilled in both business and aquaculture. "Our BlueInvest coach was the perfect match”, says Marise Almeida, NS2’s COO and CFO. “He understood our challenges not just from a business perspective, but also from a technical standpoint. That made all the difference."

The collaboration went beyond coaching; it led to joint projects, such as testing sensors in aquaponics systems. Building on these insights NS2 secured €100,000 in venture capital funding through the INNOV-ID programme.. They are now seeking additional investment to grow their business and team, and explore new markets.
