Reduced graphene oxide (rGO)-modified glassy carbon electrode is used to detect the methicillinresistant Staphylococcus aureus (MRSA) DNA by using electrochemical impedance spectroscopy. Our experiments confirm that ssDNA, before and after hybridization with target DNA, are successfully anchored on...
