Multiple, sensitive, and on-site mycotoxin detection is an essential early-warning mechanism for preventing hazards associated with food waste, safeguarding human health, preserving the environment. We synthesized a "turn-on" FRET aptamer sensor based on unique fluorescence quenching substrate recognition characteristics of Ag NTs (energy receptors) Fe3O4@TiO2 NP donor) to detect multiple toxins using single diagnostic approach. The addition AFB1 OTA resulted in change intensity at 510 650 nm, which can be employed simultaneous limits 0.94 ng mL-1 (R2 = 0.997) 0.54 0.995), respectively. aptasensors have been successfully applied determination grain oil samples high recovery rates. approach provides novel possibilities development sensitive selective fluorescent potential applications aptamer-recognized multifunctional biosensing.

In this study, green fluorescent carbon quantum dots (CQDs) with remarkable stability, water solubility, and biocompatibility were synthesized from hazelnut husk (HH) waste material using a novel approach by the pyrolysis method. The optical properties of HH-CQDs characterized UV-Vis fluorescence spectroscopy (PL), while their structural various techniques, including transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), X-ray diffraction (XRD), photoelectron (XPS). TEM images revealed that had spherical shape diameters ranging 2 to 10 nm. yield these CQDs was measured as 0.04. Furthermore, very effective at finding aflatoxin B1 (AFB1) resonance energy transfer (FRET) mechanism, clear emission peak seen 451 photoluminescent evaluated under pH conditions, showing blue shift increased intensity 9-10, suggesting potential use in pH-sensitive sensor applications. This study demonstrates selective sensitive detection AFB1 HH-CQDs, strong linear relationship (R² = 0.9936) between concentration range 25-250 ppm, high accuracy real food samples, 81.56 % corn, 98.64 milk, 95.73 peanuts. eco-friendly cost-effective synthesis method offers promising alternative for samples utilizing create valuable analytical tools.
