Abstract: ABSTRACT Biopolymer Gum-Derived Carbon Quantum Dots for Selective Acetone Detection and Method of Preparation Thereof The present invention relates to Gum Tragacanth-derived carbon quantum dots (GT-CQDs) and a method for preparation thereof. The GT-CQDs comprise a substantially sp²-hybridized graphitic carbon framework surrounded by oxygen-containing surface functional groups including hydroxyl (-OH) and carboxyl (-COOH) groups, imparting aqueous dispersibility, colloidal stability, enhanced fluorescence properties, and molecular recognition capability. The GT-CQDs are prepared by a single-step, surfactant-free hydrothermal process involving hydrothermal carbonization of Gum Tragacanth, followed by cooling, filtration, and purification. The hydrothermal treatment is carried out at approximately 250°C for about 45 minutes to obtain GT-CQDs exhibiting superior structural integrity, enhanced graphitization, favourable electronic characteristics, and fluorescence performance. The GT-CQDs selectively interact with acetone through intermolecular hydrogen bonding and photo-induced electron transfer (PET), thereby exhibiting selective fluorescence quenching towards acetone relative to other volatile organic compounds.
