“…This technique can be used to design a receptor that that performs recognition and high-specificity detection, depending on the functional monomer, its shape, and its size. [17][18][19] Such receptors have many advantages, such as stability, robustness to chemicals and extremes of temperature, non-toxicity, and eco-friendliness. However, the polymer matrix is an insulator that hinders electron transfer between the electrolyte and the electrode, leading to low signal levels.…”

In this study, to enhance selective and sensitive salbutamol detection based on the carbon plate electrode was modified with the novel-molecularly imprinted polymer (MIP) combined with reduced graphene oxide (RGO). RGO/MIP was prepared by polymerization containing methacrylic acid as a monomer and salbutamol as a template. The modified electrode was observed surface morphology by FE-SEM, tested performance by an electrochemical technique which was investigated both cyclic voltammetry (CV) and amperometry (AMP) mode. The performance of the modified electrode was compared between MIP and RGO/MIP electrode, which the RGO/MIP electrode was demonstrated at 4.16 nA/ppm of sensitivity higher than 0.91 nA/ppm of MIP electrode. There was a limit of detection (LOD) of the RGO/MIP electrode at 0.83 ppm lower than the MIP electrode. Moreover, RGO/MIP electrode was dynamic ranges from 1 to 1000 ppm, exhibited stability, repeatability, fast response, and high selectivity for salbutamol detection.
