Fig. 4. (a) ECL performances of flexible MIP-ECL sensors after they were incubated in separate solutions of 2.5 mM lactate mixed with different interferences each at a concentration of 250 mM. Error bars represent standard deviations, n ≥ 3. (b) Evaluation of the stability of the proposed sensor, accomplished by performing a continuous scanning for 20 cycles apiece after elution (green) and then incubation with 20 mM lactic acid (red). (c, d) ECL intensity changes of the flexible MIP-ECL sensor after it was incubated with a solution of 10 mM lactate undergoing repeated bending with (c) different radii and (d) different numbers of cycles at a fixed radius.
