This study presents the pequi (Caryocar coriaceum) as a new biomass source for carbon dots synthesis. The almond, usually discarded, was used precursor in one-step hydrothermal green synthesis of dots. Pequi-based (PQ-CDs) exhibited an estimated height around 8 nm, with hydroxyl, carbonyl, and amino functional groups confirmed by FTIR, bright blue emission, quantum yield 17.9%. PQ-CDs were employed fluorescent sensors Fe3+ ions, based on quenching fluorescence interaction ions. sensor demonstrated linear relationship between increase ion concentration, LOD 1.16 μmol L-1, well below maximum concentration drinking water established WHO. are cost-effective highly sensitive alternative ions detection samples from Cariri region.

Abstract BACKGROUND This study aimed to develop a simple and eco‐friendly method for synthesizing fluorescent stable carbon dots (CDs) using natural precursors. A one‐step hydrothermal approach was employed mixture of lemon ginger juice as the source. The resulting CDs were characterized evaluate their structural, optical, biocompatibility properties potential biomedical sensing applications. RESULTS Transmission electron microscopy (TEM) analysis revealed that had quasi‐spherical morphology with an average particle size 9.797 ± 1.87 nm. exhibited fluorescence quantum yield 27.7% excitation‐dependent emission, maximum excitation emission wavelengths at 400 480 nm, respectively. X‐ray diffraction (XRD) confirmed amorphous nature CDs, showing characteristic peak 28.61°. Fourier transform infrared (FTIR) spectroscopy photoelectron (XPS) identified abundant hydroxyl, carboxyl, carbonyl functional groups on surface CDs. Dynamic light scattering (DLS) determined hydrodynamic 47.7 15.57 nm zeta −13.88 1.73 mV, indicating good dispersion charge stability in aqueous solutions. thermal structural characterization synthesized thermogravimetric (TGA), differential scanning calorimetry (DSC), Brunauer–Emmett–Teller (BET) stability, phase transition behavior, mesoporous nature. demonstrated excellent several months under ambient conditions without turbidity or precipitation. Cytotoxicity assay HeLa MCF‐7 cell lines high viability ≥86%, low toxicity biocompatibility. CONCLUSION successful synthesis from juices provides green sustainable nanomaterial development. Their toxicity, favorable optical make them promising candidates bioimaging, drug delivery, biosensing © 2025 Society Chemical Industry (SCI).
