The increasing demand for innovative, sustainable, and functional food packaging solutions has led to the exploration of polyaniline (PANI) carbon nanodots (CNDs) as promising materials smart packaging. This study investigates potential PANI/CND composites electrochemical sensing alcohols, a key indicator spoilage in products. By leveraging unique properties PANI, conducting polymer, fluorescence activity CNDs, we propose dual-function material capable real-time monitoring alcohol levels, which are often released during fermentation or degradation food. integration PANI with CNDs enhances material’s sensitivity stability, offering cost-effective, environmentally friendly, responsive solution freshness detection. mechanism allows rapid, non-destructive testing, providing consumers producers an efficient tool assess product quality safety. work paves way development intelligent systems that can not only detect but also actively contribute preservation, reducing waste improving

Abstract Ciprofloxacin (CIP) is a widely used antibiotic, and its presence in water bodies poses risk due to resistance conventional wastewater treatment processes. The accumulation of such pharmaceuticals can disrupt aquatic ecosystems, harm life, contribute ecological imbalances. Therefore, the degradation CIP immense environmental significance. This study presents microwave-assisted catalytic antibiotic drug using nanocomposites carbazole copolymerized with pyrrole (PCz-co-PPy) thiophene (PCz-co-PTh). PCz-co-PPy PCz-co-PTh were synthesized through an ultrasound-assisted method. resulting characterized spectral morphological analyses. FT-IR UV–Vis spectroscopy confirmed successful intercalation copolymerization, while FESEM images revealed chain-like morphology. These copolymer employed as microwave-active catalysts for degradation, achieving optimal efficiency 95% within 21 min PCz-co-PPy-50/50 PCz-co-PTh-50/50 at 600 W microwave power. followed pseudo-first-order kinetics, rate constants calculated 0.031 −1 , 0.020 0.030 0.056 0.071 PCz, PPy, PTh, PCz-co-PPy-50/50, nanocomposites, respectively, 50 mg l solution. attributed formation microwave-induced active species, including hot spots, electrons (e − ), holes (h + superoxide radicals (•O 2 hydroxyl (•OH). Scavenger analysis verified that •OH •O play crucial role degradation. A possible mechanism pathway nanocomposite system proposed.
