Two novel sensors were developed for the determination of sucrose: An electrochemical sensor using glassy carbon electrode modified with cupric oxide (CuO)/multiwall carbon nanotubes (MWCNTs) nanocomposite (CuO/MWCNTs/GCE) and an electropolymerized molecularly imprinted polymer modified multiwall carbon nanotubes/glassy carbon electrode (MIP/ MWCNTs/GCE) [1,2]. Every two sensors were successfully applied for determination of sucrose in sugar beet juice samples, exhibiting their potential as fast and accurate sensors. The fabricated sensors are in good agreement with those from the HPLC method for the sucrose detection, demonstrating that the developed sensors have great potential for the practical usage for real sugar beet samples. In comparison, for determination of sucrose MIP/ MWCNTs/GCE is the most selective sensor made so far. This sensor with a limit of detection 3 µmol L-1 sucrose, provides an efficient way for eliminating interferences from compounds with similar structures to that of sucrose.
