The construction process of the MIPs/GR-MWCNTs/CS-SNP/gold electrode is shown step by step in Scheme 1. First, 10 mLof CS-SNP have been added on electrode surface and dried at RT. Second, 10 mL of GR-MWCNTs have been added on the CS-SNP/gold electrode and dried at RT. After that, pyrrole polymer film with the neomycin template was deposited onto the modified electrode using CV in 0.1 mol L
