In 2021, copper electrochemical sensors were adopted by Nanya Technology Corporation, a famous semiconductor manufacturer, to monitor the copper concentration in the waste water produced from their factories.

Field Investigation of Heavy Metals in Romblon, Philippines Mapúa University, a leading engineering institution in the Philippines, conducted a field investigation of heavy metal contamination in river systems on Romblon Island, an offshore province of the Philippines. The research team deployed the MAS G1 water quality sensing system in combination with the M-series ion-specific test strips, which are capable of detecting copper (Cu), nickel (Ni), chromium (Cr), zinc (Zn), arsenic (As), and lead (Pb) ions. This in situ monitoring approach enabled real-time assessment of heavy metal concentrations in the river environment.
