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.

“…Carbonaceous nanomaterials, especially the surface-modified carbon nanotubes, have been increasingly applied for electroanalytical chemistry recently because of their exceptional electrical, optical, thermal, mechanical, and chemical properties, as well as the flexibility to be associated with numerous chemical compounds to form new nanocomposites. − Moreover, because the pristine CNTs are insoluble in most aqueous solutions and certain organic solvents, it is also essential to conduct surface modification to improve their solubility . The biomolecule-tethered CNTs nanocomposites have been previously reported for electrocatalysis, biomedical imaging, drug delivery, and photocatalysis. , The modification of multiwalled CNTs (MWCNTs) has been especially focused, compared with the single-walled ones, as the intensive functionalization on the outer surface of CNTs may not affect the fast electron transfer through the inner graphitic walls. ,, …”

Collision at a single molecule level was achieved based on the nanoimpact of an individual pyrroloquinoline quinone (PQQ) modified multiwalled carbon nanotube (MWCNT) at the carbon fiber ultramicroelectrode (C UME). Electrocatalytic amplification of the current responses was observed when the PQQ-modified MWCNT collided with C UME in the presence of hydrazine (N2H4) in a Tris-HCl buffer solution, which was also supported by the conventional cyclic voltammetry and chronoamperometry techniques. The enhanced catalytic oxidation of N2H4 was due to the “addition-elimination” redox cycling mechanism of PQQ/PQQH2, where the oxidation of N2H4 occurred together with the reduction of PQQ under an external bias, and the formed PQQH2 intermediate would be reoxidized back to PQQ simultaneously. The average collision current, duration, and charge for PQQ-modified MWCNT at 1.0 V vs Ag/AgCl were 105 pA, 0.45 ms, and 49 fC, respectively. As a result, the turnover frequency of electrocatalytic oxidation of N2H4 by PQQ was calculated to be 54 s–1. In this regard, the proposed individual carbon nanotube collision method can not only serve as a promising sensing technique to detect biochemical species, but more importantly provide a robust approach to determine the intrinsic catalytic activity as well.
