“…The electrodes for coulometric detectors should have large active surface and are most commonly made of a porous carbon. Recently, coulometric detectors with renewable working material of glassy carbon microbeads [85] and carbon felt [86] have been developed. The potentiostatic mode is usually used for the coulometric detection.…”

The definition of antioxidants (AOs), their classification and properties as well as electrochemical sensor systems for AOs analysis are briefly discussed. The analytical capabilities of coulometric titration with electrogenerated titrants as sensor systems for AOs determination have been considered in detail. The attention focused on the individual AO quantification that was mainly used in the pharmaceutical analysis and estimation of total antioxidant parameters (total antioxidant capacity (TAC), ferric reducing power (FRP) and ceric reducing/antioxidant capacity (CRAC)) allowing the fast screening of the target samples including their quality control. The main advantages of coulometric sensor systems are pointed out. The selective quantification of individual AO in a complex matrix using a combination of chromatography with coulometric or coulometric array detection under potentiostatic mode is discussed. The future development of coulometric sensor systems for AOs analysis is focused on the application of novel coulometric titrants and the application of coulometric detection in flow injection analysis.

Electrochemical detection has a great potential in microfluidic systems due to its easy miniaturization without losing analytical performance. In addition, the use of nanomaterials in electroanalysis improves sensitivity, selectivity, and reproducibility. The topic of this review is the use of nanomaterials (nanoparticles, nanotubes, graphene) in electrochemical detection for capillary electrophoresis and microfluidic systems (microchips and paper based analytical devices). This review covers from 2015 up to now and it is a continuation of our previous review, also published in Electrophoresis journal. The following aspects of the surveyed articles are mainly addressed: type of nanomaterial, protocol of working electrode preparation (composite, drop casting and others), advantages of nanomaterial employment and application field (clinical, food, environmental and home security). The use of nanomaterials is still an interesting approach to improve the analytical performance of electrochemical detection based on microfluidic devices. Along the review, readers will find new protocols for working electrode modification, new carbon nanomaterials and promising applications in the aforementioned fields.
