“…During the last decade, molecularly imprinted polymer (MIP), a man-made predesigned cross-linked structure organic nanomaterial with specific recognize sites complementary in size, shape and functional groups with the template molecule, has been developed as a powerful medium to enhance selectivity in electrochemical sensor [20]. Recently, various nanomaterials involving multi-walled carbon nanotubes (MWCNTs) and graphene [21], metal nanoparticles [22], metal oxides [23] and semiconductors [24] have been used in the construction of imprinted sensor to improve their analytical performance.…”

“…The proposed sensor presented a lower limit of detection, compared to the values found elsewhere [15,17,34,37]. Although a lower limit of detection and higher linear range was obtained for the method described by Nezhadali [38], the novelty of the proposed sensor is that it enabled simultaneous determination of the analytes.…”

Hemodialysis is the most commonly used method for the treatment of chronic kidney disease. In this procedure, some patients use diuretics to control weight gain and blood pressure. In this work, a voltammetric sensor based on a glassy carbon electrode modified with carbon nanotubes (GCE/MWCNT) is described for the simultaneous determination of the diuretics hydrochlorothiazide (HCT) and triamterene (TRT). The oxidation of the diuretics on the GCE/MWCNT surface was observed at 1.01 and 1.17V for HCT and TRT, respectively, allowing simultaneous determination, which was not possible with the unmodified glassy carbon electrode. The GCE/MWCNT electrode provided 6-fold and 10-fold gains in anode peak intensity for HCT and TRT, respectively, compared to the unmodified electrode. After optimization of the conditions (pH, accumulation time, and accumulation potential), analytical curves were constructed for the analytes in the range from 1.0 × 10 to 2.0 × 10molL. The detection limits for HCT and TRT were 2.8 × 10 and 2.9 × 10molL, respectively. A high performance liquid chromatography method with diode array detection was also developed for the determination of HCT and TRT in hemodialysis samples, for comparison with the electroanalytical method.

“…They are complementary to the template in shape, size, and chemical functionality . High adsorption capacity, low cost, ease of preparation, and inertness toward organic solvents, acids, or bases are the main features of MIPs . MIPs are frequently used as catalysts, enzyme mimics, SPE adsorbents, and also in sensors and drug delivery systems .…”

This paper describes the synthesis of a molecularly imprinted polymer by chemical oxidation of pyrrole as the functional monomer, and at the presence of guaifenesin as the template. The prepared polymer was used as adsorbent in molecularly imprinted solid‐phase extraction followed by spectrophotometric determination. Different parameters in the solid‐phase extraction including sample pH, adsorbent weight, washing solution, and elution solvent were studied to determine optimum conditions for isolation and enrichment of guaifenesin. The results showed guaifenesin was quantitatively adsorbed on the molecularly imprinted polymer at pH 6.0 and completely eluted with an ethanol–water solution (50% v/v). An enrichment factor of four with satisfactory recoveries (87.0–95.0%) was obtained. The solid‐phase extraction columns could be used for up to six consecutive elution‐loading cycles without significant decreases in the analyte recoveries. The method had a dynamic range of 3.0 × 10−6–1.5 × 10−4 mol/L with a limit of detection and limit of quantification of 1.4×10−6 and 4.5×10−6 mol/L, respectively. The proposed procedure was used for the extraction and determination of guaifenesin in different pharmaceutical formulations, with satisfying results being achieved.
