“…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.

“…It may be interpreted that the adsorptive behavior of SDS changes from monomer adsorption to monolayer adsorption with the SDS concentration increasing, resulting in the increase of OPP adsorbed to the electrode surface. The SDS concentration of 1.0 mol/L may have reached the critical micelle concentration value [38], for the synergistic effect of the adsorption and the accumulation of SDS on the electrode surface. However, the peak current decreases when further increasing SDS concentration.…”

The electrochemical behavior of ortho-phenylphenol (OPP) at a disposable electrode (an improved wax-impregnated graphite electrode) in the presence of sodium dodecyl sulfate (SDS) was studied for the first time. The results demonstrated that the electrocatalytic oxidation process of OPP was accompanied with two-charge-two-proton transference. The electronic transmission coefficient (  ) and diffusion coefficient (D R ) for OPP were calculated to be 0.8126 and 3.61 × 10 2 cm 2 /s, respectively. The electrochemical signal was apparently improved by SDS at the disposable electrode and the oxidative peaks current was proportional to the concentration of OPP over the range from 1.0 × 10 9 to 4.0 × 10 6 mol/L with the detection limit of 8.7 × 10 10 mol/L. This novel and highly sensitive method can be successfully applied to detect OPP in the orange rind sample. sodium dodecyl sulfate, electrochemical, determination, ortho-phenylphenol, disposable electrode

“…It may be interpreted that the adsorptive behavior of SDS changes from monomer adsorption to monolayer adsorption with the increasing of SDS concentration, resulting in the increase of topotecan hydrochloride adsorbed to the electrode surface. The SDS concentration of 10 nmol/L may have reached the critical micelle concentration (CMC) value [35], for the synergistic effect of the adsorption and the accumulation of SDS on the electrode surface. However, the peak current decreased with further increasing SDS concentration.…”

A sub-picomole level topotecan hydrochloride determination method was first proposed using sodium dodecyl sulfate (SDS) as a sensitized reagent at a novel disposable electrode (an improved wax-impregnated graphite electrode). The effects of different kinds of surfactants on the electrochemical response to topotecan hydrochloride were examined. The results indicate the electrochemical signal was apparently improved by SDS. At optimal conditions, the oxidative peak current increased linearly with the logarithm of concentrations for topotecan hydrochloride in the ranges of 2.0 × 10 12 to 1.0 × 10 11 mol/L and 8.0 × 10 11 to 8.0 × 10 10 mol/L with a detection limit of 6.4 × 10 13 mol/L. The proposed method could be applied in determining topotecan hydrochloride in urine. topotecan hydrochloride, electroanalysis, sodium dodecyl sulfate (SDS), disposable electrode
