SOUTH BEND – St. Mary’s College has announced that researchers at the college and at the University of Notre Dame have developed a process that can screen for counterfeit medication.

The tool, made of paper, is the size of a business card and will be used in developing countries where up to 30 percent of the drugs are counterfeit.

Researchers focused initially on malaria, antibiotics, anti-viral and anti-tuberculosis medications. St. Mary’s said color changes on the paper indicate suspicious material.

St. Mary’s has applied for a patent.
