A signal cascade amplification strategy based on RT-PCR triggering of a G-quadruplex DNAzyme for a novel electrochemical detection of viable Cronobacter sakazakii

An effective and sensitive DNAzyme method for electrochemical detection of viable Cronobacter sakazakii was designed. The detection method is based on RT-PCR and cascade amplification of ribozymes to achieve rapid detection of viable Cronobacter sakazakii.
