Various types of electrochemical methods; containing, differential pulse voltammetry (DPV), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in order to probe the characteristics of the sensor toward CB was employed. The selectivity, real sample analysis (efficiency), the linear concentration range, and the detection limit of CB at the MIP/NiO-NPs/SPCE were evaluated by DPV method. FT-IR spectroscopy was applied in order to characterize the synthesized CB-MIP and non-molecular imprinted polymers (NIP). Scanning electron microscopy (SEM) and BET (Brunauer-Emmett-Teller) techniques were used for surface morphology and porosity properties of CB-MIP and NIP. A linear range was presented by the sensor for CB concentration between 2-150 µM with detection limit (S/N=3) of 0.35 µM. The sensor is able to selectively detect the CB molecules over the potential interferences. The sensor was used to determine CB in the real sample with acceptable results.}, keywords = {Molecular imprinted polymer,Celestine blue,Nickel oxide nanoparticles,Screen Printed Carbon Electrode}, url = {https://www.analchemres.org/article_133041.html}, eprint = {https://www.analchemres.org/article_133041_57895fd8fdd94709a5b2b3cc874f9083.pdf} }
