“…With this method, it is possible to detect common saccharides in extracts from plants [27]. Several HPLC procedures are available for the determination of sugars in urine [10,12,16,[28][29][30]. Some methods are based on refractive index detection [28], which has the advantage of being universal.…”

“…The basis of the response mechanism to glucose at these transition metals was suggested to involve the electrontransfer mediation of the multivalent metal redox couple of the anodized metal electrodes [15]. In general, copper-based electrode materials are of interest for analysis of carbohydrates because of its superior capabilities in terms of range of response, detection limit, and particularly stability in comparison to others [17,18]. Also, Cu-based microelectr-odes have been applied for analysis of carbohydrates [19,20].…”

Copper nanoparticles (CuNPs) encapsulated by polymeric stabilizer of polyvinylpyrrolidone (PVP) (noted as PVPCuNPs) were simply prepared and used to construct an enzymeless glucose sensor on a solid substrate. Sensing and assay performance of the CuNPs-based sensor to glucose were evaluated in detail. Cyclic voltammetry (CV), chronoamperometry (I -t) and flow injection amperometry (FIA) revealed a high sensitivity, excellent stability, and good reproducibility in the glucose determination at þ 0.45 V, which was 200 mV more negative than those in former reports. A detection limit as low as 1.0 Â 10 À8 M (signal-to-noise ¼ 3) and a linear range of 1.0 Â 10 À7 M to 5.0 Â 10 À3 M were obtained in this study.

“…A copper electrode in direct current amperometric mode was employed for detection of mannitol, xylose and lactulose in urine [141], which is a useful alternative to HPLC with pulsed amperometric detection at a gold electrode. A copper hydroxide carbon electrode was used for detecting several sulfur-containing compounds in alkaline media [142].…”

As general trends in current development of chemical analysis, including electroanalysis, one can indicate a search for methods fast and multianalyte, for miniaturized measuring devices, mechanization and automation of analytical processes. In all these trends a significant role is played by measurements in flow conditions. The major advantage of flow electroanalysis is a possibility of utilizing a kinetic discrimination in potentiometric measurements and enhancement of mass transport in voltammetric techniques. Flow injection techniques provide shortening of time of a single analytical determination due to reproducible use of transient signal from the detector without need of obtaining a steady-state equilibrium signal. Electrochemical detection in HPLC gives often improved selectivity and detection limit for electroactive solutes, whereas in capillary electrophoresis it allows a convenient design of portable, integrated chips for field application. This review presents state-of-the -art of flow electroanalysis based on 226 cited literature references
