(A)-Nyquist plots of the impedimetric calibration curve resulted from the successful binding events taking place at the surface of the phage-based biosensor. Measurements were conducted at different counts of the E. coli O157:H7 within the concentration range of 101 to 107 CFU/ml. (B) The relationship between the change in the Rct values and the increase in the bacterial counts. (C) The Randles equivalent electrical circuit designed for extracting the EIS parameters.
