Cyclic voltammogram during the surface functionalization process of the MC-LR biosensor. (a) SPCE Type 2 with acetone cleaning for 90 min, (b) SPCE Type 2 with ethanol cleaning for 90 min, (c) SPCE Type 4 with acetone cleaning for 90 min, and (d) SPCE Type 4 with ethanol cleaning for 90 min. The redox probe solution (50 ml) of 5 mM [Fe(CN)6]3-/4- in 10 mM PBS was used.
