“…All these data help to prove the excellent electrochemical behavior of CB nanoparticles, making it an exciting alternative carbon nanomaterial for construction of electrochemical sensors and biosensors. Currently, the use of CB for sensing purposes involves the electrochemical determination of pharmaceutical [4,[34][35][36][38][39][40][41][42][43], environmental contaminants [44][45][46][47][48][49][50][51][52][53][54][55][56][57], food additives [58][59][60][61], biomolecules [46,[62][63][64][65][66][67][68][69][70][71], and nicotine [12].…”

Carbon black (CB) is a nanostructured material widely used in several industrial processes. This nanomaterial features a set of remarkable properties including high surface area, high thermal and electrical conductivity, and very low cost. Several studies have explored the applicability of CB in electrochemical fields. Recent data showed that modified electrodes based on CB present fast charge transfer and high electroactive surface area, comparable to carbon nanotubes and graphene. These characteristics make CB a promising candidate for the design of electrochemical sensors and biosensors. In this review, we highlight recent advances in the use of CB as a template for biosensing. As will be seen, we discuss the main biosensing strategies adopted for enzymatic catalysis for several target analytes, such as glucose, hydrogen peroxide, and environmental contaminants. Recent applications of CB on DNA-based biosensors are also described. Finally, future challenges and trends of CB use in bioanalytical chemistry are discussed.

“…The unsaturated coordination of these atoms renders them particularly efficient in the activation of fast charge transfers occurring via inner-sphere mechanisms, i.e., in promoting electrocatalytic processes. Among the different carbon-based nanosized materials, carbon black nanoparticles (CB) [15][16][17][18][19][20] show properties very similar to carbon nanotubes, being however characterized by a much lower price, which allows envisaging possible large-scale production of cost-effective devices.…”

Screen-printed electrode (SPE) modified with carbon black nanoparticles (CB) has been tested as a new platform for the stable deposition of caffeic acid (CFA) on the electrode surface. The electrochemical performance from varying the amount of CFA/CB composite has been tested with respect to NADH determination. The electrocatalytic activity of CFA/CB has also been compared with that of SPEs modified by a single component of the coating, i.e., either CFA or CB. Finally, glycerol dehydrogenase, a typical NADH-dependent enzyme, was deposited on the CFA/CB coating in order to test the applicability of the sensor in glycerol determination.

“…The relationship between the anodic peak potential (E pa ) and log ν is also shown in Figure 2A-II. On observing the slope obtained from the linear relationship (equation: E = 8.38 × 10 -1 ± 4.57 × 10 -3 + 6.74 × 10 -2 ± 3.46 × 10 -3 log ν, r 2 = 0.992 (r 2 is the coefficient of correlation)) established by the Laviron equation, 43,44 it is possible to identify the number of electrons involved in the BPA oxidation (slope = 2.303 RT/αnF, where α = 0.5 for irreversible processes (α is the electron transfer coefficient, n is the electron transfer number, F is faraday constant, R is universal gas constant, T is temperature)). 45 According to the results obtained in this study, the number of electrons involved is two (n = 2, Scheme 1).…”

This paper describes a new and simple electrode for the determination of bisphenol A (BPA) in different plastic samples using carbon paste electrode (CPE) modified with a trihexyltetradecylphosphonium tetrachloromanganate(II) ([P 6,6,6,14 + ] 2 [MnCl 4 2− ]) magnetic ionic liquid (MIL/CPE). Electrochemical characterization of MIL/CPE by cyclic voltammetry and electrochemical impedance spectroscopy indicated that MIL facilitated the electron transfer. Using squarewave voltammetry (SWV) under optimized conditions, the calibration curve showed a linear range for BPA from 2.0 to 53.0 μmol L-1 , with limit of detection (LOD) of 0.87 μmol L-1. The proposed electrode demonstrated good precision with coefficients of variation of 4.5% (intra-day, n = 10), 2.0% (inter-day, n = 5) and 1.5% (electrode-to-electrode repeatability, n = 3). Recoveries of 93.0 to 101.1% demonstrated that the method is suitable for practical applications.
