Description
Carbon, the most abundant and versatile element, has played a significant role in scientific innovations, forming the backbone of material science and nanotechnology. This study presents the first reported simultaneous photogenic synthesis of carbon nanospheres (CNS) integrated with silver nanoparticles (CNS@AgNPs) using Coriander sativum seed extract for sucralose detection. The CNS@AgNPs formation, mediated by oleic acid from the extract, was confirmed with GCMS analysis. The morphology of the CNS@AgNPs was characterized using SEM, TEM, XPS, XRD, Raman, BET, Diffuse Reflectance Spectroscopy (DRS), and Thermogravimetric analysis (TGA). The fabricated GE/Nafion/CNS@AgNPs electrode demonstrated an intense oxidation peak current at +0.7V, with Differential Pulse Voltammetry (DPV) showing a linear response from 2.0 to 14?M, with a LOD and LOQ of 0.2?M and 0.62?M (R2=0.998), respectively. The Density Functional Theory (DFT) studies revealed key mechanistic insights, including the methanol cleavage energy (~3.135נ103eV) and HOMO-LUMO differences between neutral sucralose and its cationic form. Monte Carlo (MC) simulations confirmed favourable adsorption energy (?52.739kcal/mol) with specific binding interactions (3.3578.653 influencing electron transfer pathways. This eco-friendly approach presents the potential of sustainable materials for developing efficient electrochemical sensors for detecting artificial sweeteners in real samples. 2025 Elsevier B.V.
