Detection of NLP: (A) control experiment; (B) calibration curve of fluorescence Vs different concentrated NLP; (C) The specificity of the proposed method. Here, the concentration of BSA, Salmonella, E. Coli, and GI-NLPs was 0.0012 µg mL⁻¹, 0.0011 µg mL⁻¹, 0.001 µg mL⁻¹ and 0.001 µg mL⁻¹, respectively
