“…In terms of electrochemical performance, which corresponds to the key aims of this paper, until now very few applications are reported in the literature [9,[23][24][25][26] with the majority not explaining the behaviour and potentialities of carbon black. One notable contribution has been from Arduini et al [8] who were the first to compare the electroanalytical performance of carbon black (CB N220) "film" deposited onto screen-printed electrodes with its electrochemical performance explored towards ferricyanide, epinephrine, norepinephrine, benzoquinone and NADH; their results shown significantly enhanced electrochemical activity when compared with screen-printed electrodes without the modification of carbon black.…”

Graphical abstract Imparting improvements in electrochemical sensorsThree different carbon black materials have been evaluated as a potential modifier, however, only one demonstrated an improvement in the electrochemical properties. The carbon black structures were characterised with SEM, XPS and Raman spectroscopy and found to be very similar to that of amorphous graphitic materials. The modifications utilised were constructed by three different strategies (using ultrapure water, chitosan and dihexadecylphosphate). The fabricated sensors are electrochemically characterised using N,N,N',N'-tetramethyl-para-phenylenediamine and both inner-sphere and outer-sphere redox probes, namely potassium ferrocyanide(II) and hexaammineruthenium(III) chloride, in addition to the biologically relevant and electroactive analytes, dopamine (DA) and acetaminophen (AP).Comparisons are made with an edge-plane pyrolytic graphite and glassy-carbon electrode and the benefits of carbon black implemented as a modifier for sensors within electrochemistry are explored, as well as the characterisation of their electroanalytical performances. We reveal significant improvements in the electrochemical performance (excellent sensitivity, faster heterogeneous electron transfer rate (HET)) over that of a bare glassy-carbon and edge-plane pyrolytic graphite electrode and thus suggest that there are substantial advantages of using carbon black as modifier in the fabrication of electrochemical based sensors. Such work is highly important and informative for those working in the field of electroanalysis where electrochemistry can provide portable, rapid, reliable and accurate sensing protocols (bringing the laboratory into the field), with particular relevance to those searching for new electrode materials.

“…Carbon black is widely used as carbon material to construct sensors for analyte detection in gaseous phases, for fuel cell, lithium and sodium battery development 9–12. However, until 2011, few applications have been reported using carbon black as electrode material for analyte detection in solution 7,8,13–17. In our previous works, we have developed a SPE modified by a “film” of a stable dispersion of commercial available carbon black (CB N220) in acetonitrile.…”

In this paper screen‐printed electrodes (SPEs) bulk modified with carbon black (CB) or with CB dispersion in DMF:water were developed and characterized. We have demonstrated by cyclic voltammetry, SEM and electrochemical impedance spectroscopy that an increase of CB amount on the working electrode surface increases the electrochemical performances of CB‐SPE. The CB‐SPE was tested with ferricyanide, epinephrine, benzoquinone and H2O2 demonstrating in any case an enhancement of electrochemical activity. For H2O2 amperometric detection, a sensitivity of 241.4±5.7 mA M−1 cm−2 and 1.46±0.06 mA M−1 cm−2 was obtained, respectively, for CB‐SPE and bare SPE.

“…A sensor based on polyethylenegraphitized CB as an electrochemical detector in a highperformance liquid chromatography (HPLC) analytical system was developed. It showed a higher signal-to-noise ratio for several compounds tested such as phenol, chlorophenols and hydroquinone [14]. The suitability of CB for biosensor applications was demonstrated with tyrosinase to produce a biosensor that was challenged in amperometric mode with catechol.…”

A novel matrix based on commercially available carbon black (CB) N220 and didodecyldimethyl ammonium bromide (DDAB) was shown to be a reliable support for direct electron transfer reactions between screen printed electrode (SPE) and Fe(III)-heme proteins. Cytochrome c (cyt c), myoglobin (Mb), horseradish peroxidase (HRP) and cytochromes P450 (CYP 51A1, CYP 3A4, CYP 2B4) generated well-shaped cyclic voltammograms on SPE/CB/ DDAB electrodes (both in solution and in immobilized state). The attractive performance characteristics of CB modified electrodes are advantageous over single-walled carbon nanotubes (SW CNT) based ones. The achieved direct electrochemistry of heme proteins on CB/DDAB-modified electrodes provided successful elaboration of the immunosensor for cardiac Mb. The immunosensor showed applicability for diagnostics of myocardial infarction displaying significant difference in cardiac Mb content of human blood plasma samples taken from the corresponding patients.
