Frederick professor's discovery patented

July 13, 2008

FREDERICK, Md. - Dr. Joseph A. Rosebrock, assistant professor of anatomy and physiology at Frederick Community College, recently received a patent for inventing a way to stabilize hydrogen peroxide at an alkaline or basic pH. The patent protects the intellectual property, or knowledge, of how to achieve a more stable indicator in certain types of scientific tests.

Peroxidase is an enzyme often used as an indicator chemical in testing for infectious agents and diseases such as E. coli and bird flu. Stabilizing hydrogen peroxide enables the development of more sensitive tests and clearer measurements of color, light or fluorescence, which can result in enhanced detection of viruses, bacteria, or cancer proteins.

Co-inventors of the patented discovery were Tom Woerner, Dr. Charles Hewitt and Heidi Woerner. The patent is owned by SurModics Inc. (formerly BioFX Laboratories Inc.).
