Figure 2: Represents the sample fits of Impedance (Z) vs. Frequency (ω) data to the proposed circuit model using the software ZView™. (a) Represents the plot of reactance (ZII) vs. resistance (ZI), for 0 hr, 2 hr and 4 hr for E. coli in Ampicillin at 8 mg/ml as a sample data set (b) Represents the sample fit (smooth line) using the circuit model for the 4 hr reading (line with dots) of E. coli in Ampicillin at 8 mg/ml.
