A Current–voltage curves of the etched PET film before (black) and after (red) Mal-PEI modification. B, C Current–voltage curves of Mal-PEI-modified PET film before and after additions of α2-6 (B) or α2-3 C sialyllactose solutions with different concentrations. D Comparison of the current reduction ratio of the films treated with α2-6 (black), α2-3 (red) sialyllactose and Neu5Ac (green) solutions (0.1 μM). E, F Concentration-dependent transmembrane ionic current decrease ratio (ΔI/I0) of the films upon treatment with α2-6, α2-3 sialyllactose, and Neu5Ac solutions (E) or α2-6 sialyllactose, galactose and lactose solutions F. G–I Concentration-dependent transmembrane ionic current decrease ratio (ΔI/I0) of bare PET film G, PEI-modified PET film (H), or acetylated Mal-PEI-modified PET film I treated with α2-6 (black) or α2-3 (red) sialyllactose solutions. All tests were conducted at 20 °C using 0.01 M NaCl solution as the electrolyte and repeated three times to obtain the average change ratios of the ionic current.
