NS2

About

Science-driven, made in Portugal

Vision

Sustainable management of water resources through innovative technology.

Mission

To provide functional testing solutions that enable the sustainable management of water resources and aquatic environments.

About

Founded in 2019 and based in Portugal, NS2 develops electrochemical sensors, pre-calibrated test strips and a handheld reader that bring lab-grade results to the water's edge. No sample transport, no reagents to mix — one drop, a result in minutes.

Our roots are in UCIBIO at NOVA School of Science and Technology and Egas Moniz School of Health Science, where our electrochemical sensing research began.
