Detecting and quantifying mycotoxins using LFIA are challenging due to the need for high sensitivity accuracy. To address this, a dual-mode colorimetric-SERS was developed detecting deoxynivalenol (DON). Rhodium nanocores provided strong plasmonic properties as SERS substrate, while silver nanoparticles created electromagnetic "hotspots" enhance signal sensitivity. Finite element modeling optimized field intensity, Prussian blue generated distinct at 2156 cm-1, effectively reducing background interference. This achieved detection limit of 4.21 pg/mL, 37 times lower than that colloidal gold-based (0.156 ng/mL). Machine learning algorithms, including ANN KNN, enabled precise classification quantification contamination, achieving 98.8% accuracy an MSE 0.57. These results underscore platform's potential analyzing harmful substances in complex matrices demonstrate important role machine learning-enhanced nanosensors advancing technologies.
