Performance of the RFD-EC1 DNAzyme in milk, apple juice and drinking water samples. (A) Fluorescence signal of the DNAzyme in reaction buffer alone (RB), diluted milk alone (milk), diluted milk spiked with E.coli (milk + EC), diluted apple juice alone (AJ), diluted apple juice spiked with E. coli (AJ + EC), drinking water alone (DW), drinking water spiked with E. coli (DW + EC). The error bars are based on the standard deviation of triplicate experiments. (B) A representative fluorescent image of each of the experiments described in part A.
