Square wave voltammetry allows determination of electron transfer kinetics between the electrode and the redox probe, and this can be incorporated with the new technique cSWV. (Top) Plots of normalized current (i_p/f) vs 1/frequency (1/f) could provide the apparent electron transfer rates from the plot maximum and are displayed for ATP and tobramycin sensors. (Bottom) To compare electrode kinetic information obtained from cSWV, traditional SWV was performed in a selected range of frequencies for the same E-AB sensors. Similar trends are observed with the two techniques for the states with and without a target.
