“…Similar to macrocyclic metal complexes, some watersoluble dyes consist of macrocyclic conjugate structure, and have been widely used as mediators to catalyze the electrooxidation of NO, for example eosin b [82], toluidine blue [39], thionine [41] and brilliant cresyl blue [40]. Through a simple electro-polymerization procedure, we prepared a sensitive electrochemical NO sensor based on polyazocarmine Bfunctionalized MWCNTs.…”

“…The sensitive sensing system is also well-designed to further improve the analytical performance of NO sensor. There are two major channels for the design of NO sensitive surface, one is to employ redox mediator, such as macrocyclic metal complexes [31][32][33][34][35][36][37][38], watersoluble dyes [39][40][41][42][43] or metalloproteins [44][45][46][47][48][49], and the other is to introduce nanomaterials for the construction of the sensing interface.…”

Electrochemical sensing has been demonstrated to represent an efficient way to quantify nitric oxide (NO) in challenging physiological environments. A sensing interface based on nanomaterials opens up new opportunities and broader prospects for electrochemical NO sensors. This review (with 141 refs.) gives a general view of recent advances in the development of electrochemical sensors based on nanomaterials. It is subdivided into sections on (i) carbon derived nanomaterials (such as carbon nanotubes, graphenes, fullerenes), (ii) metal nanoparticles (including gold, platinum and other metallic nanoparticles); (iii) semiconductor metal oxide nanomaterials (including the oxides of titanium, aluminum, iron, and ruthenium); and finally (iv) nanocomposites (such as those formed from carbon nanomaterials with nanoparticles of gold, platinum, NiO or TiO 2 ). The various strategies are discussed, and the advances of using nanomaterials and the trends in NO sensor technology are outlooked in the final section.

“…Another application was as mediator in electrochemical biosensors [19,20]. However, the electrochemical behaviour of BCB has been investigated only by using polarography [21] or transparent thin layer spectroelectrochemistry [22] and reports concerning the electropolymerisation of BCB are just two to our knowledge [23,24] with only brief characterisation.…”

A selective and highly sensitive electrochemical method, based on a poly(brilliant cresyl blue)-modified activated glassy carbon electrode, was developed for the simultaneous determination of hydroquinone (HQ) and catechol (CT). The modified electrode was characterized by cyclic voltammetry (CV). It was found that the modified electrode showed an excellent catalytic activity and enhanced reversibility toward the oxidation of both HQ and CT in 0.1 M phosphate buffer solution (PBS, pH 7.0). The peak-to-peak separations ( E p ) between oxidation and reduction waves in CV were decreased significantly from 360 and 285 mV at the bare electrode, to 59 and 56 mV at the poly(brilliant cresyl blue) modified electrode for HQ and CT respectively. Furthermore, the redox responses from the mixture of HQ and CT were easily resolved in both CV and differential pulse voltammetry (DPV). The oxidation peak currents of HQ and CT were linear up to 250 μM with the detection limits (S/N = 3) of 60 and 56 nM for HQ and CT, respectively. The developed sensor was successfully examined for real sample analysis with tap water and it showed a stable and reliable recovery data with high reproducibility.
