Figure 3b shows that in the preparation of a control non-imprinted polymer (NIP), no peak at ∼+ 0.40 V was observed
Figure 3c shows DPV of the as-prepared MIP (prior to template removal) and NIP modi fi ed rGO-AuNPs/SPCEs
Figure 3. Electropolymerization of (a) MIP from a solution containing 5 mM p-PDA and 1 mM NLX in phosphate-citrate buffer, (b) NIP from a solution containing 5 mM p-PDA in phosphate-citrate buffer, and (c) DPV  voltammo-grams of MIP and NIP modi fi ed rGO-A
Figure 5. Variation of DPV peak current of NLX as a function of (a) mole ratios of NLX to p-PDA, (b) number of electropolymerization cycles, and (c) pH of the pre-polymerization solution
