چکیده مقاله
This review article provides a comprehensive overview of the latest advances in the preparation, properties, and sensing performance of waste-derived nanomaterials (NMs). This article is novel and informative in its scope, since: (a) different approaches for the synthesis of NMs are investigated, considering the advantages and disadvantages of each one; (b) the efficiency of waste-derived NMs in optical sensors is evaluated; (c) it is discussed how waste precursor chemistry can dictate NM surface functionalities and resulting optical selectivity and sensitivity; (d) it is reviewed how heteroatom doping can tune the electronic structure, bandgap, defect states, and optical absorption of waste-derived NMs; (e) different optical sensing mechanisms of waste-derived NMs, including fluorescence enhancing/quenching, inner-filter effect, Förster resonance energy transfer, and surface-state modulation, are assessed; and (f) current trends and future bottlenecks in relation to the synthesis and use of waste-derived NMs in optical sensing platforms are illustrated. © 2026
