“…The figures of merit were determined, and the best sensor was assigned for the experimental investigation work. To achieve excellent analytical performance for the optimized MCPE and stabilize the electrogenerated intermediates and products, it is a common practice to add very small concentrations from anionic surfactants such as sodium dodecyl sulfate (SDS) [28,29]. Moreover, SDS adsorption on the electrode and solubilization of the electrochemically active compounds in the micellar aggregates enables the measuring of low concentration levels of DTZ using this developed simple and cost-effective method.…”

Diltiazem (DTZ) hydrochloride, a calcium channel blocker compound, is a very well‐known drug used by many clinicians to treat important diseases playing a role in increased morbidity and mortality among adults worldwide, namely hypertension, cardiac arrhythmia, and ischemic heart disease (angina pectoris). These diseases are a common public health concern, implying that the construction of a specific, accurate, and simple sensor for DTZ determination is needed. Herein, an innovative, portable, and sensitive modified carbon paste electrode (MCPE) was seamlessly developed based on the affordable green compound N‐bromosuccinimide (NBS) as a sensing material and tricresyl phosphate as a solvent mediator for the voltammetric determination of DTZ. The proposed NBS‐MCPE exhibited an excellent electrocatalytic activity towards the oxidation of DTZ molecules in a phosphate buffer solution of pH 5.0 in presence of 20 μM sodium dodecyl sulfate to improve the developed sensor performance. The sensor was found to respond linearly to the DTZ drug over a wide concentration ranging from 1 μM to 300 μM with a low limit of detection. LSV and EIS measurements were also used to scrutinize our sensor, in addition to using scanning electron microscopy and energy dispersive X‐ray analysis techniques for its surface morphology inspection before and after soaking in the drug‐containing solution. The applicability of the proposed sensor for the rapid, sensitive, and selective determination of DTZ in pharmaceutical preparation and human urine samples was assessed and the obtained results were compared with that of the reported HPLC analytical method.

Electropolymerization nanofilm was prepared by cyclic voltammogram with 6N,N-diallylamino-1,3,5-triazine-2,4-dithiol monosodium (DAN) on the AA5052 surface in 0.15M NaNO 2 at 10 C, then octyl-triethoxysilane (OTES) film was fabricated on the poly(6N,Ndiallylamino-1,3,5-triazine-2,4-dithiol) nanofilm (PDA) covered AA5052 surface by self-assembling method to obtain the composite polymeric nanofilm (C-PDA/OTES). The composite polymeric nanofilm was characterized by means of FTIR spectra, scanning electron microscope (SEM), contact angle, and potentiodynamic polarization. The results showed that the C-PDA/OTES covered surface was more homogenous, compact, hydrophobic compared with PDA covered surface and had excellent protection efficiency.

Voltammetric sensors are simple, powerful, and cheap equipment with easy principles, which have been widely used in electrochemical studies to investigate the properties of the electroactive species. Surfactants are frequently used in the construction of voltammetric sensors to enhance the sensitivity and selectivity of the sensor, which significantly impacted the electrode function in terms of dissolving organic compounds, creating a specific orientation of molecules on the surface of the electrodes, and enhancing electron transfer reactions. This review focuses on the recent contributions of surfactants in the development of efficient voltammetric sensors. In addition, other ingredients commonly employed alongside surfactants, such as nanomaterials, conducting polymers, and composite materials, have been discussed. The comprehension of these aspects can guide the expansion and the use of surfactants in the electrochemical sensing scope.
