a CV for HeLa cell on (dashed lines) ITO and (plain curves) thin film of PANI/ITO, cell number was 5.8 × 105 mL−1. b Microscopy image of HeLa on (i) ITO incubated for 48 h, (ii) thin film of PANI/ITO incubated for 24 h and (iii) thin film of PANI/ITO incubated for 48 h. c CV for HeLa cells on PANI/ITO at different cell numbers, (plain curves) 2.4 × 105, (dashed lines) 4.8 × 105, (dotted lines) 7.2 × 105, (dash dot dash lines) 9.6 × 105. Inset linear plot of reduction current peak as a function of cell number. The scan rate was 0.1 V s−1 and the temperature was 37 ± 0.5 °C. d CV of HeLa cells on PANI/ITO at different scan rate (plain curves) 20, (dashed lines) 50, (dotted lines) 100, (dash dot dash lines) 150 and (dash dot dot dash lines) 200 mV/s. Inset linear plot of reduction current peak as a function of scan rat. Data is shown as the mean ± standard deviation of three different experiments
