“…Annually, more than 700,000 persons commit suicide, making it the fourth most prevalent cause of death among those aged 15 to 29 . Amitriptyline (AMT), a tricyclic antidepressant, has gained attention in depression treatment, resulting in excessive production and prescription, which led to the subsequent presence in various environmental matrices due to inadequate removal by wastewater treatment plants. , Apart from its therapeutic efficacy in depression, it also exhibits side effects such as impaired vision, fainting, or sedation and its overdose can cause respiratory, neurological, and cardiovascular ill effects . Despite relatively low environmental concentrations of AMT, even at ng/L levels, can adversely impact organisms like zebrafish and rodents, , indicating a need for precise analytical methods for detection …”

In recent years, the issue of pharmaceutical contaminants in water bodies has emerged as a significant environmental concern owing to the potential negative impacts on both aquatic ecosystems and human health. Consequently, the development of efficient and eco-friendly methods for their determination and removal is of paramount importance. In this context, the development of a surfactant ensemble sensor has been explored for hard-to-sense amphiphilic drug, i.e., amitriptyline. Herein, a pyrene-based amphiphile chemoreceptor was synthesized and characterized through various spectroscopic techniques such as 1 H, 13 C NMR, single-crystal XRD, FTIR, and ES-mass spectrometry. Then, dodecanoic acid (DA) and a pyrene-based receptor in a THF/water solvent system were used to generate reverse micelle-based self-aggregates of SUPRAS (SUPRAmolecular Solvent). The structural aspects, such as morphology and size, along with the stability of the SUPRAS aggregates were unfolded through spectroscopic and microscopic insights. The present investigation describes a synergistic approach that combines the unique properties of premicellar concentration of supramolecular solvent with the promising potential of pyrene-based receptor for enhanced amitriptyline extraction with simultaneous determination from water (LOD = 12 nM). To evaluate the effectiveness of the developed aggregates in real-world scenarios, experiments were conducted to determine the sensing efficiency among various pharmaceutical pollutants commonly found in water sources. The results reveal that the synergistic nanoensemble exhibits remarkable sensing ability, toward the amitriptyline (AMT) drug outperforming conventional methods.
