“…Various major methods have been applied to the detection of ED such as immunoassay, HPLC, and mass spectrometry . But the electro-analytical method has many advantages over them such as simple, inherent high selectivity, fast detection, and low cost. − In this regard, different electrode materials were developed to modify conventional electrodes, such as Fe 3 O 4 -doped nanoporous carbon, Pd/N-doped reduced graphene, DNA aptamer immobilized gold electrode chip, enzyme biosensor, and conductive biochar nanoparticles . But these materials have their own limitations.…”

Here, the effect of morphology on the electrocatalytic activity of metal–organic framework (MOF) was investigated. Post synthetic gold (Au) insertion was done into hollow PCN-222 (HPCN-222) and solid PCN-222 (SPCN-222) frameworks by a simple hydrothermal method. The crystalline nature, chemical composition, and morphologies of the synthesized MOFs were characterized by PXRD, XPS, and TEM. Electrochemical characterizations were done by cyclic voltammetry and electrochemical impedance spectroscopy. The excellent electrocatalytic activity of highly small-sized Au(0) with the enhancement of electrical conductivity through a hopping mechanism combined with a hollow structure and high surface area in the HPCN-222 MOF hugely alters the electrochemical properties. Overall, a better electrocatalytic surface area, charge transfer coefficient, and catalytic activity were generated at the modified electrode. The hollow structure MOF showed better electrocatalytic activity than solid structured MOF. The AuHPCN-222 modified glassy carbon electrode (AuHPCN-222/GCE) electrochemical sensor was employed for the analytical analysis of estradiol (ED) in an optimum experimental condition. AuHPCN-222 showed selective and better electrocatalytic activity toward ED than GCE. The differential pulse voltammetric measurements by the fabricated sensor showed two linear determination ranges for ED; those are 0.01–1 and 1–220 μM. The measured limit of detection (m-LOD) was found to be 0.5 nM with the highest sensitivity of 2.2 μA μM cm–2. The analytical performances for the detection of ED in human urine and serum samples were done with reasonable recoveries (98%–103%) using the standard addition method. Also, the sensor showed better reproducibility and repeatability with stability.

“…For the determination of L-DOPA, the LOD value obtained in this study was lower than that of some reported analytical methods [85,[89][90][91][92]. Although some studies had a lower LOD than the proposed method, they had a limited working range than the proposed method [28,84,58,69,[88][89][90]92]. The proposed method exhibited a lower LOD value for the determination of PAR than L-DOPA.…”

For determination of levodopa (L‐DOPA) and paracetamol (PAR), selective, effective and sensitive electrochemical sensor based on 3,5‐diamino‐1,2,4‐triazole (35DT) on glassy carbon (GC) electrode was reported. The DPV method was used to obtain the oxidation peak current of L‐DOPA which increased linearly with its concentration at the range of 1–99 μM and 99–480 μM. The linear relationship between the concentration of PAR and its peak current was obtained in the range of 0.3–55 μM and 55–475 μM. The limit of detection values for PAR and L‐DOPA were found to be 0.1 and 0.25 μM, respectively. Satisfactory results were obtained in pharmaceutical samples.

For a happy and healthy life, there should have a balance of flight-to-flight hormones, i.e, adrenaline (AD). The necessity of determination of AD is inevitable for the diagnosis of associated diseases with it. For this purpose, N-doped graphene supported α-Co(OH)2 (denoted as NrGO/α-Co(OH)2) was synthesized via a hydrothermal process, where α-Co(OH)2 acted as an active site and NrGO provided a better defective surface for immobilized α-Co(OH)2 nanoparticles. The as-prepared nanocomposite altered the electronic configuration due to its defective nature, which played an important role to increase the stability, surface area and electron transfer capability. As a result, NrGO/α-Co(OH)2 demonstrated remarkable analytical performances toward AD with a lower limit of detection (14.7nM), wide linear range (0.5-800µM), and good sensitivity (115.983 µA mM−1 cm-2). The CA response time was obtained as 2.2 s. The proposed sensor showed precious selectivity during AD detection in presence of coexisting biomolecules such as DA, AA, UA, TY, 5-HT, and NE, and 50-fold excess of common ions such as Na+, K+, Ca2+, Mn2+, Fe2+, CO32-, and SO42-. Furthermore, it also provided long-term stability, good reproducibility and repeatability with practical feasibility in the urine sample. Importantly, the effect of pH was studied in detail on AD oxidation.
