Rapid Sensing of Toxic Metals with a New Hybrid Inorganic Material (HIM) Through pH Changes (Technology #: 052407-01)

Lehigh University is actively looking for partners to commercialize a new method for rapidly identifying the presence of toxic heavy-metal contaminants in groundwater. Decades of mining for heavy metals such as lead, zinc and cadmium have produced abandoned mines across the U.S., each of which has the potential to pollute nearby groundwater sources....
