o Baltimore-Based InfraTrac Lands Investments from TEDCO, Saffron Hill Baltimore -- InfraTrac, a Baltimore-based company that uses near-infrared spectroscopy to detect and prevent counterfeiting, said that it has received an undisclosed amount of funding from the Maryland Technology Development Corp. (TEDCO), through its Maryland Technology Transfer Fund, as well as from Saffron Hill Ventures. InfraTrac's technology, which the company licenses from the University of Maryland School of Pharmacy in Baltimore, tags products such as pills, powders, liquids, vaccines and plastics. Companies can then use an optical chemical analyzer to immediately determine whether or not the products are genuine. The company's software also can detect "grey market" products, such as Medicare drugs that end up in a retail pharmacy. http://www.infratrac.com/
