“…ZIF-8, made up of 2-methyl imidazolate and zinc ions, has become an attractive modifier in the fabrication of electrochemical sensors. To improve its low electrical conductivity, ZIF-8 has been coupled with polymers [ 71 ], metal and metal oxide nanoparticles [ 72 ] and carbon materials [ 73 ]. Reduced graphite oxide (RGO) is a derivative of graphene [ 74 ] and has been used In the fabrication of extremely sensitive electrochemical sensors due to its high electronic conductivity, mechanical strength and electron transfer rate [ 75 ].…”

Selective serotonin re-uptake inhibitors (SSRIs) are one of the most commonly prescribed classes of antidepressants used for the treatment of moderate to severe depressive disorder, personality disorders and various phobias. This class of antidepressants was created with improved margins of safety. However, genetic polymorphism may be responsible for the high variability in patients’ responses to treatment, ranging from failure to delayed therapeutic responses to severe adverse effects of treatment. It is crucial that the appropriate amount of SSRI drugs is administered to ensure the optimum therapeutic efficacy and intervention to minimise severe and toxic effects in patients, which may be the result of accidental and deliberate cases of poisoning. Determining SSRI concentration in human fluids and the environment with high sensitivity, specificity and reproducibility, and at a low cost and real-time monitoring, is imperative. Electrochemical sensors with advanced functional materials have drawn the attention of researchers as a result of these advantages over conventional techniques. This review article aims to present functional materials such as polymers, carbon nanomaterials, metal nanomaterials as well as composites for surface modification of electrodes for sensitive detection and quantification of SSRIs, including fluoxetine, citalopram, paroxetine, fluvoxamine and sertraline. Sensor fabrication, sensor/analyte interactions, design rationale and properties of functional material and the electrocatalytic effect of the modified electrode on SSRI detection are discussed.

“…However, these methods employ various reagents, require specific skills to operate sophisticated instruments, and are time consuming and thus not practical for in situ analysis. Alternatively, electrochemical methods offer an attractive approach for hydrazine measurements due to their low cost, simple preparation, rapid response, high sensitivity, and potential as portable devices. − For these reasons, we selected electrochemical methods for hydrazine measurements for this present study. There are a plethora of electroanalytical methods that have been developed to provide electrochemical sensing of hydrazine based on the platform of the modified carbon electrode. − In addition, we have reported the utilization of the composite material of electrochemically reduced graphene oxide (ErGO) and conductive polymer-modified electrode for uric acid detection, but it remains interesting to explore our developed sensing platform for the detection of novel electroactive substance hydrazine.…”

In this study, hydrazine sensors were developed from a composite of electrochemically reduced graphene oxide (ErGO) and poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), deposited onto a glassy carbon electrode (GCE). The structural properties, electrochemical characterization, and surface morphologies of this hydrazine sensor were characterized by Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, electrochemical impedance spectroscopy (EIS), and scanning electron microscopy (SEM). In addition, the proposed hydrazine sensor also demonstrates good electrochemical and analytical performance when investigated using cyclic voltammetry (CV), differential pulse voltammetry (DPV), and amperometry techniques under optimal parameters. Using these investigated parameters, DPV and amperometry were chosen as techniques for hydrazine measurements and showed a linear range of concentration in the range of 0.2−100 μM. The obtained limits of detection and limits of quantitation for hydrazine measurements were 0.01 and 0.03 μM, respectively. In addition, the proposed sensor demonstrated good reproducibility and stability in hydrazine measurements in eight consecutive days. This fabricated hydrazine sensor also exhibited good selectivity against interference from Mg 2+ , K + , Zn 2+ , Fe 2+ , Na + , NO 2 − , CH 3 COO − , SO 4 2− , Cl − , ascorbic acid, chlorophenol, and triclosan and combined interferences, as well as it depicted %RSD values of less than 5%. In conclusion, this proposed sensor based on GCE modified with ErGO/PEDOT:PSS displays exceptional electrochemical performance for use in hydrazine measurements and have the potential to be employed in practical applications.
