“…The electrooxidation of DOP leads to formation of semiquinone as intermediate product where phenolic groups of DOP are not present in dissociate form and the amino groups is present in protonated form [52] which mechanism includes the transfer two electrons and two protons and thus radical formation is expected and at pH 7.0 this process rapidly occurs, facilitating the oxidation [53]. So, the electrochemical response is based on DOP oxidation with the metal center Fe (III) in the internal [54].…”

A synthesis of β-cyclodextrin (β-Cd) functionalized with polyamide dendrimer PAMAM G.0 complexed with silver and potassium hexacyanoferrate (III) forming a mixed-valence complex (β-Cd-PAMAM-Ag/Fe) was proposed. This material was characterized by scanning electron microscopy (SEM), infrared spectroscopy (FT-IR), X-Ray diffraction (XRD), Energy Dispersion Spectroscopy (EDS) and Electron Paramagnetic Resonance (EPR). The hybrid complex was electrochemically investigated using cyclic voltammetry and some parameters (electrolyte, concentration of electrolyte, pH and scan rate) were evaluate in order to obtain optimum analytical responses. The β-Cd-PAMAM-Ag/Fe material was successfully applied in the electrocatalytic oxidation of dopamine (DOP) using Cyclic Voltammetry (CV) and Square Wave Voltammetry (SWV).

“…[128] An important number of sensors and biosensors based on this PB(A)s activity has been reported, including the detection of glucose, [129] glutathione, [130] dopamine, [131] hydrazine, [132] nitrites, [133] and sulfites. [134] Finally, the redox properties of PB(A)s were also used for electrocatalysis aiming to detect pollutant compounds dangerous for the environment and human health, such as hydrazine, [135], [136] explosives, [137], [138] nitrites and sulfites, [133], [139], [140] as well as numerous drugs. [141], [142], [143], [144] PB(A)s can be further beneficial and interesting in connection to their redox properties at the nanoscale for all above-mentioned applications and a huge amount of work has been performed in this area.…”

“…With this purpose, the researchers have found various PBA to the design and construc-tion of electrochemical sensors. 69,72,110,111,116,142,150 The PBAs display a significant role in these sensors since they allow the electro-oxidation of sulfite to sulfate, and that of nitrite to nitrate, reducing the overpotentials and improving analytical parameters such as sensitivity, the limit of detection and selectivity.…”

Prussian blue and its analogs (PBA) form an attractive family of materials for sensing and biosensing applications. Due to their open framework structure their electrochemical behavior is closely linked to the intercalation of alkaline ions. Moreover, these compounds show a clear peroxidase activity that makes them excellent transducers in biosensors based on H 2 O 2 quantification. In this review, we present in a progressive manner an overview of the structure, composition, and synthesis of PBA. Subsequently we approach the current trends in the use of PBA in the field of electrochemical sensors, providing a critical discussion on their electrochemical behavior and the electrocatalytic activity toward H 2 O 2 electrooxidation and electroreduction, along with the determination of toxic, hazardous compounds and drugs.
