N2  -  A novel promising electrochemical nicotine (NIC) sensor was achieved  through three different ways. Firstly by electrodeposition of Ce-Nanoparticles  on a carbon paste electrode (CPE), secondly by chemical mixing of TiO2  nanoparticles with carbon paste and/or finally by using Ag nanoparticles.  Electrochemical techniques including cyclic voltammetry (CV), electrochemical  impedance spectroscopy (EIS) and linear sweep voltammetry (LSV) were used  in the present investigation in addition to analysis techniques like scanning  electron microscope (SEM) and Energy Dispersive X-Ray (EDX) techniques, in  both aqueous and micellar media. NIC Measurements were investigated in  Britton-Robinson (B-R) buffer solution of pH range (2.0-8.0) containing  (1.0mM) sodium dodecylsulfate (SDS). The detection limit for CNMCPE is  9.43{u00D7}10-8M, for NTMCPE is 1.34{u00D7}10-8M, and for SNMCPE is 1.2{u00D7}10-8M. In  addition, good satisfactory results were achieved for the detection of NIC in real  samples as urine samples and different brands of commercial cigarettes
