Superbug, meet kryptonite

University of Idaho researchers are taking a new approach to detect new resistant pathogens, such as multiple (formerly methicillin) resistant Staphylococcus aureus (MRSA). Wusi Maki and colleagues have developed nanoelectronic biosensors that take just three hours instead of three days to spot resistant bacteria. The system could eventually replace the conventional culture dish and chemiluminescence detection. "Our electronic detection capability is approximately 1000 times more sensitive than the chemiluminescence technologies currently being used in clinical laboratories," says Maki.
