Figure 3. — The ratio of OSWV peak current in the presence of different concentration of acrylamide (I_p) to that in the absence of acrylamide (I_p,0) as a function of the acrylamide concentration. The currents were measured at the peak potential in OSWV curves in the solution with no analyte E_p,0. Results obtained for electrodes modified with SWCNT, E_p,0=46 mV, n=4, 2.2<SD<7.7 ( ) and SWCNT/Hb, E_p,0=44 mV, n=3, 0.9<SD<4.4 ( ).
