Developing highly sensitive biosensors for MRSA bacterial detection

Nosocomial infection is a growing problem in Canadian hospitals, these bacteria can kill as many as 8,000 patients per year, and the expenses reach at least $100 million annually. Clostridium difficile (C. difficile) and methicillin‐resistant Staphylococcus aureus (MRSA) are among the most common bacteria. For example, C. difficile has killed more than 600 people in Quebec alone between 2003 and 2005. The control of the spread of bacteria to multiple patients in hospitals and the efficacy of treatment will be improved with early detection of bacteria.
