Cover Story: The increasing resistance to carbapenems, an important sub-class of beta-lactam antibiotics, is a major concern in the healthcare community. Carbapenem resistant bacteria have been found in the environment and food supply chains, where it has the potential to infect humans through direct or indirect contact. Rapid detection for preventative and control measures should be developed. This study utilized a gold-nanoparticle-based plasmonic biosensor for the parallel detection of the carbapenem resistance genes blaNDM-1 and blaOXA-1. To explore the field portability, DNA extraction was completed using a boiling method. The results showed a correlation of measurements between a spectrophotometer and an RGB (visual) cellphone app with high selectivity and sensitivity, showing potential for point-of-care use.
