“…However, most of the reported sensors comprise more complex and time-consuming modification processes either for the formation of the Sb film or for the pretreatments required when the sensor was developed in a non-disposable platform. Contrasting the performance of the 2D Sb-SPCE with that achieved by bismuthene carbon-based screen-printed electrode (2D Bi-SPCE) [12], it can be stated that the 2D Bi-SPCE provided lower LODs (0.06 and 0.07 µg L − 1 for Pb(II) and Cd(II) respectively), but narrower linear ranges (up to 25 µg L − 1 for Pb(II) and Cd(II)) and lower sensitivities (2.76 and 2.32 nA V µg − 1 L for Pb(II) and Cd(II), respectively) for both metal ions. Moreover, it should be taken into account that 2D Sb-SPCE allows working at more acidic pH and that the potential window available for the voltammetric determination of metal ions using a 2D Sb-SPCE is much wider than that offered by 2D Bi-SPCE since the Sb oxidation peak appears at more positive potentials than Bi oxidation peak.…”

“…The exfoliating method for Sb, Sb 2 S 3 , Sb 2 Se 3 and Sb 2 Te 3 was adapted from a previously reported method [12,20]. Briefly, 0.5-1.0 g of the selected material were dispersed in 120 mL of 1:1 isopropanol:water solution.…”

“…However, although the implementation of bismuthene and antimonene as voltammetric sensors presents a great potential, scarce literature is found on the subject [11]. Our group recently reported an exfoliated layered bismuth (2D Bi) based screen-printed electrode (SPE) for the stripping determination of cadmium(II) and lead(II), which demonstrated a superior analytical performance than typical bismuth-based electrodes by providing limits of detection as low as 0.06 and 0.07 μg L − 1 for Pb (II) and Cd(II), respectively [12]. Similar results were also reported by Lazanas et al [13].…”

“…To improve the performance of the biosensor, the number of bacteria, the amount of cross-linker (glutaraldehyde), and the incubation time applied were optimized. María A Tapia et al [59] prepared a bismuthene-modified carbon-based screen-printed electrode with the advantage of the strong features of exfoliated layered bismuth and differential pulse anodic stripping voltammetry for metal ions detection. Vincenzo Mazzaracchio et al [60] designed screenprinted electrodes for sodium detection in sweat.…”

Recent advances in electrochemical devices have sparked exciting opportunities in the healthcare, environment, and food industries. These devices can be fabricated at low costs and are capable of multiplex monitoring. This overcomes challenges presnted in traditional sensors for biomolecules and provides us a unique gateway toward comprehensive analyses. The advantages of electrochemical sensors are derived from their direct integration with electronics and their high selectivity along with sensitivity to sense a wide range of ionic analytes at an economical cost. This review paper aims to summarize recent innovations of a wide variety of electrochemical sensors for ionic analytes for health care and industrial applications. Many of these ionic analytes are important biomarkers to target for new diagnostic tools for medicine, food quality monitoring, and pollution detection. In this paper, we will examine various fabrication techniques, sensing mechanisms, and will also discuss various future opportunities in this research direction.

“…It is notable that as an electrochemical sensing platform, the screen-printed electrode (SPE) has been largely attracted because of merits like easier application, portability, and affordability [30,31]. Hence, the screen-printed technology significantly contributes to the transition from the conventional unwieldy electrochemical cells to the portable miniaturized electrodes, satisfying the on-site analysis requirements [32,33].…”

This paper presents a sensitive simultaneous detection procedure for Sudan I and bisphenol A based on the multiwalled carbon nanotubes (MWCNTs)/Co3O4 nanocomposite modified screen-printed graphite electrode (SPGE). This MWCNTs/Co3O4 nanocomposite was prepared by the hydrothermal technique, and characterized by Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD). The electrochemical properties of MWCNTs/Co3O4 nanocomposite modified SPGE were analyzed by cyclic voltammetry (CV), differential pulse voltammetry (DPV), chronoamperometry (CHA), as well as linear sweep voltammetry (LSV). From the electrochemical results, a synergy between MWCNTs and Co3O4 nanoparticles (NPs) was detected as improved interfacial electron transfer, which was accompanied by a greater catalytic function for electrochemical oxidation of Sudan I. Based on the optimized condition, MWCNTs/Co3O4/SPGE exhibited the linear dynamic ranging between 0.05 and 600.0 μM detection of Sudan I with a limit of detection (LOD) 0.02 μM. Also, the as-prepared electrode was assessed for simultaneous detection of Sudan I and Bisphenol A. In the course of electrooxidation processes of these analytes, two complete peaks at 380 and 520 mV were observed on the modified electrode. At the end, utility of this new electrochemical sensor was performed to determine Sudan I and Bisphenol A in some real samples with good accuracy and precision.
