A carbon paste electrode (CPE)/Cu nanowire (Cu NW)/poly(1-ethyl-3-methylimidazolium methyl sulfate) based sensor was successfully fabricated by the electro-polymerization of 1-ethyl-3-methylimidazolium methyl sulfate (EMIMS) onto the surface of Cu nanowires-modified carbon paste electrode. The morphology and chemical nature of Cu NWs were characterized by FTIR, FE-SEM, TEM, XRD techniques. The CPE/CuNWs/poly(EMIMS) showed an electrocatalytic activity toward the determination of etilefrine hydrochloride (ET-HCl) in the 0.11?M buffer solution of phosphate at pH 7.0. The CPE/CuNWs/poly(EMIMS) showed an excellent limit of detection (LOD) 2.3 ?M over the linear dynamic range of 0.1 to 1.3 ?M. The prepared CPE/CuNWs/poly(EMIMS) has exhibited high stability, good sensitivity, and low detection limit for the determination of ET-HCl. The validity of this advanced method was checked by applying in the blood plasma samples, with satisfactory results. This novel CPE/CuNWs/poly(EMIMS) can be an attractive material for the applications in biomedical and sensor fields.
