The Water Quality ICORP team aims to further develop and commercialize miniature electrochemical sensors that can detect—at low–cost and instantaneously—low levels of heavy metals (including lead, cadmium, mercury, chromium, and copper), water acidity (pH) and nutrients in drinking water and other fluids using a single drop of liquid.

The sensors were developed by Chang, who explains that they use a screen-printed electrode with surface modification techniques, and electrochemical sensing methods.
