Electrochemical response (a) of HeLa cells using a scan rate of 100 mV s−1, temperature of 37 ± 0.5 °C, and cell number of 5.8 × 105 mL. b Cyclic voltammograms of HeLa cells at different scan rates (dash dot dash lines) 25 m V s−1, (dotted lines) 50 m V s−1, (dashed lines) 100 m V s−1, (solid lines) 200 m V s−1. c Relationship of peak current with the cell number (dashed lines) 2.4 × 105 cells mL−1, (dotted lines) 3.6 × 105 cells mL−1, (dashed lines) 4.8 × 105 cells mL−1, (plain curves) 6 × 105 cells mL−1. d Linear plot of reduction current peak as a function of cell number. The scan rate was 100 mV s−1 and the temperature was 37 ± 0.5 °C. Data are the mean ± standard deviation of three different experiments
