“…For this reason, pH: 7.0 was chosen for the whole study (E peak � À 1.4 V). The P4 reaction has been reported [25] to involve reduction of the double bond conjugated to the carbonyl moiety. On the other hand, as can be seen in Figure 1b, the P4 peak current is almost independent of the accumulation potential applied.…”

For the determination of progesterone (P4) electroanalytical studies were performed using mercury electrode (HMDE) and screen-printed boron-doped diamond electrode (BDD-SPE). The effects of pH, supporting electrolyte, accumulation potential and time (E acc , t acc ) were studied in both systems. The optimum conditions were: i) HMDE: pH 7,0; E acc : À 0,1 V and t acc : 40 s, ii) BDD-SPE: 0,5 mol L À 1 H 2 SO 4 ; E acc : 0,0 V and t acc : 120 s. Under these conditions, the detection limit was 3.1 μg L À 1 for HMDE and 45.6 μg L À 1 for BDD-SPE. Both methods were validated and applied in the P4 determination on pharmaceutical formulations and milk samples.

“…In the existing body of literature, various studies have been conducted to investigate the cleaning and activation of the BDD electrode. These studies used the application of potentials in both the anodic and cathodic directions, albeit in different solutions [58]. Boron-doped diamond (BDD) electrodes, when subjected to varying levels of boron doping, exhibit distinct variations in binding energies and carrier densities, which have significant implications for their utilization in semiconductor applications.…”

Hormones regulate several physiological processes in living organisms, and their detection requires accuracy and sensitivity. Recent advances in nanostructured electrodes for the electrochemical detection of hormones are described. Nanostructured electrodes’ high surface area, electrocatalytic activity, and sensitivity make them a strong hormone detection platform. This paper covers nanostructured electrode design and production using MOFs, zeolites, carbon nanotubes, metal nanoparticles, and 2D materials such as TMDs, Mxenes, graphene, and conducting polymers onto electrodes surfaces that have been used to confer distinct characteristics for the purpose of electrochemical hormone detection. The use of aptamers for hormone recognition is producing especially promising results, as is the use of carbon-based nanomaterials in composite electrodes. These materials are optimized for hormone detection, allowing trace-level quantification. Various electrochemical techniques such as SWV, CV, DPV, EIS, and amperometry are reviewed in depth for hormone detection, showing the ability for quick, selective, and quantitative evaluation. We also discuss hormone immobilization on nanostructured electrodes to improve detection stability and specificity. We focus on real-time monitoring and tailored healthcare with nanostructured electrode-based hormone detection in clinical diagnostics, wearable devices, and point-of-care testing. These nanostructured electrode-based assays are useful for endocrinology research and hormone-related disease diagnostics due to their sensitivity, selectivity, and repeatability. We conclude with nanotechnology–microfluidics integration and tiny portable hormone-detection devices. Nanostructured electrodes can improve hormone regulation and healthcare by facilitating early disease diagnosis and customized therapy.

“…Optimizing the voltammetric method's effectiveness necessitates the development of an improved electrode material. Various comprehensive studies conducted throughout the last two decades have observed that boron-doped diamond (BDD) electrode, the relatively new carbon-based form, has sparked enormous fascination as such an environment-friendly electrode material in such a variety of sectors, including chemical analysis, environmental research, biological scientific method, materials science, and etc [29][30][31][32][33][34][35][36][37][38]. BDD electrode has an extraordinarily broad potential windows in both aqueous and non-aqueous mediums, structure stability at extremes anodic & cathodic potentials, and then a great resistant to deactivation by surfaces fouling (the existence of sp 3 hybridized atoms of carbon in diamonds structures).…”

An effective electrochemical sensor was constructed using an unmodified boron‐doped diamond electrode for determination of genistein by square‐wave voltammetry. Cyclic voltammetric investigations of genistein with HClO4 solution indicated that irreversible behavior, adsorption‐controlled and well‐defined two oxidation peaks at about +0.92 (PA1) & +1.27 V (PA2). pH, as well as supporting electrolytes, are important in genistein oxidations. Quantification analyses of genistein were conducted using its two oxidation peaks. Using optimized experiments as well as instrumental conditions, the current response with genistein was proportionately linear in the concentrations range of 0.1 to 50.0 μg mL−1 (3.7×10−7−1.9×10−4 mol L−1), by the detection limit of 0.023 μg mL−1 (8.5×10−8 mol L−1) for PA1 and 0.028 μg mL−1 (1.1×10−7 mol L−1) for PA2 in 0.1 mol L−1 HClO4 solution (in the open circuit condition at 30 s accumulation time). Ultimately, the developed method was effectively applied to detect genistein in model human urine samples by using its second oxidation peak (PA2).
