“…12 Electrode modifiers such as alloys, metals, and metal oxides and the electrocatalytic enhancer like carbon-based materials, which increase the activity of the electrode material, are two important reasons that turned the focus of researchers toward the electroanalytical technique. 6 So far, electrode modifiers such as nitrogen-doped graphene oxide quantum dots (N-GOQDs), 13 Au NPs stabilized by 1-(3-sulfonatopropyl)imidazolium, 14 MoS 2 -coated SnO 2 −CNF, 15 spinel zinc ferrite nanoparticle (ZnFe 2 O 4 ), 16 chitosan-modified copper nanocubics, 17 and cadmium sulfide nanoparticles/multiwalled carbon nanotubes composite-modified gold electrode (CdSNPs/MWCNTS/ AuE) 18 were used to detect indomethacin. The current challenge is focused on optimizing the activation of GCEs to enhance their overall performance.…”

Indomethacin (IDM) is commonly prescribed for headaches, fever, and articular disease as a nonselective nonsteroidal anti-inflammatory drug (NSAID), inhibiting prostaglandin synthesis to reduce fever, inflammation, and pain. However, its extensive use has resulted in water reservoir contamination from human and veterinary waste. Recognizing the urgent need for sustainable water contamination prevention and human health concerns, researchers have focused on indomethacin detection. In response, an innovative interdisciplinary platform, merging nanoscience and electrochemical engineering, was created. Detailed examination of the structural, crystallographic features and morphological insights of the electrode modifier was conducted. The nanocomposite's hierarchical arrangement, utilizing hybrid heterojunction and quantum confinement, enables synchronized indomethacin detection with a low limit of detection (LOD) of 39.3 nM. The resulting sensor demonstrates a wide linear range (0.001−264.02 μM), along with high sensitivity, selectivity, and stability. Expanding its utility, the sensor was successfully applied to water and human urine samples, showcasing its effectiveness in monitoring the proposed platform's consistency. This advancement shows promise in enhancing the sustainable detection of indomethacin in both environmental and biological settings.

This study demonstrates the feasibility of extracting lecithin from oil industry byproducts in an eco‐friendly manner, with minimal use of water and without harmful chemicals. Liposomes can be generated directly from this extracted lecithin, enhancing the value of these byproducts and enabling the production of catalytic gold nanoparticles (AuNPs). Thin‐layer chromatography of the extracted lecithin revealed a phospholipid composition primarily consisting of phosphatidylethanolamine and phosphatidylcholine, and surface tension studies demonstrated similar behavior between the extracted and commercial lecithin. Liposome formation using sustainable lecithin (LPn) resulted in structures that were stable for at least 10 days, exhibiting a low polydispersity index (0.395) and uniform size (approximately 214 ± 7 nm). Gold nanoparticles were synthesized successfully in LPn loaded with [HAuCl4] by using different photoreduction methods: ultraviolet (UV) lamp, pulsed laser 355 nm, and sunlight irradiation. The AuNPs exhibited characteristic sizes (ranging from 5.03 to 6.78 nm) and optical properties typical of nanoparticles, including a distinct surface plasmon resonance. As a proof of concept, we also demonstrated that the synthesized AuNPs exhibited catalytic activity in UV‐induced cis‐trans isomerization reactions. Overall, the study highlights the potential of sustainable soy lecithin extraction for diverse applications, including nanoparticle synthesis and catalysis.
