Vi beskriver en elektrokemisk metod sensor analys för snabb bakteriell detektion och identifiering. Analysen omfattar en sensor array med funktionella fånga DNA oligonukleotidsonder för ribosom RNA (rRNA) artspecifika sekvenser. Sandwich hybridisering av mål-rRNA med infångningsproben och en pepparrotsperoxidas-länkad DNA oligonukleotid detektorsonden ger en mätbar amperometriskt ström.
