“…A few studies have reported about the use of some methods for glucose determination including GOx (glucose oxidase) based colorimetric methods [4][5], high performance liquid chromatography (HLPC) [6], liquid chromatography-mass spectrometry (LC-MS) [7], and potentiometry using modified carbon-based electrodes [8]. Modified carbonbased electrodes have previously been developed including zeolite-modified electrodes for the analysis of uric acid [9], Cr 3+ ions [10], creatinine [11], creatine [12]; and polymer-based electrodes for phenol analysis [13]. Nanoparticle material has also been shown to increase the selectivity and sensitivity of electrodes to analytes [14].…”

Imprinted zeolite modified carbon paste (carbon paste-IZ) electrode had been developed as a sensor to analyze blood glucose content by potentiometry. The used zeolite was Lynde Type A (LTA) that synthesized with a mole ratio of Na2O, Al2O3, SiO2 and H2O of 4:1:1.8:270, respectively while non-imprinted zeolite was prepared with a mole ratio of glucose/Si of 0.0306. Glucose was then extracted from the zeolite framework using hot water (80 °C) to produce imprinted zeolite (IZ). The carbon paste-IZ electrode prepared from activated carbon, paraffin pastilles, and IZ with a mass ratio of 5:4:1 showed the best performance. The modified electrode demonstrated the measurement range of 10–4-10–2 M, the Nernst factor of 29.55 mV/decade, the response time less than 120 s, and the detection limit of 5.62 × 10–5 M. Ascorbic acid, uric acid, urea and creatinine did not interfere on the glucose analysis by potentiometry. Comparison test with spectrophotometry showed an accuracy of (90.7 ± 1.4)% (n = 5), while the application of the electrode to analyze five spiked serum samples showed recovery of (92.2 ± 1.3)% (n = 5). The electrode was stable for up to 9 weeks (168 times usage). Based on its performance, the developed electrode can be applied to analyze glucose in human serum sample and recommended for used in the medical field.

Imprinted zeolite modified carbon paste electrode as a potentiometric sensor for glucose analysis in blood serum sample has been developed. In this study, the type of used zeolite was TS-1. Imprinted zeolite (IZ) was synthesized with mole ratio of glucose/Si of 0.0306. The modified electrode prepared by mixing activated carbon, imprinted zeolite, and paraffin granule with mass ratio 9:4:7 from the measurement in range of 10 -5 -10 -2 M is with Nernst factor of 28.6 mV/decade, and the detection limit of 4.79 x 10 -5 M. The electrode was able to respond the glucose molecules in solution quickly (<30 s), stable for more than 9 weeks (130 times usage) and selective to glucose molecules. The urea, uric acid, and creatine with various concentrations did not interfere to glucose analysis by potentiometry using the electrode. Applying of the electrode for glucose analysis in spiked blood serum samples showed that it had recovery of 91.73±3.48% (n=5), while its accuracy against spectrophotometry method as commonly used method in medical field was 90.58±4.65% (n=5). Based on its performance, potentiometry using the imprinted zeolite modified carbon paste electrode is recommended as an alternative method for routine blood glucose analysis in the medical field.

“…One method that can be used in determining rhodamine B is the electrochemical method. This method has succeeded in developing techniques for analyzing organic compounds [10], [11] as well as their degradation [12], [13]. This technique has the advantage of being easy in the preparation process, cheaper, small in size, and allows it to have a very small detection limit, and also easy to automated.…”

The modification of carbon paste electrode (CPE) with molecularly imprinted polymer (MIP) for the determination of rhodamine-B by potentiometry method has been studied. The experiments were performed using glutamic acid as a monomer. The composition of monomers, the number of electropolymerization cycles and pH of the solution were used to describe modification electrodes made (CPE-MIP's) and the electrode characteristics were evaluated. It was observed the amount of oxidation current signal increase with increasing glutamic acid concentration. The optimal polymerization molar ratio of the functional monomer to the template molecule rhodamine-B was 3:1; the maximum number of electropolymerization was 15 and the optimum pH of supporting electrolyte solution was 4.
